About this episode

Used-car pricing and trade appraisal get reframed as a data problem, not an “art.” The hosts connect thin margins, inventory turns, and lead competition to why guesswork gets expensive fast. They dig into VIN-level, condition-adjusted pricing and CRM-linked retention metrics—arguing inconsistent quotes erode trust. From DMS integrations and auction/inspection data to automated repricing with guardrails and timed follow-up, the episode shows how systems replace gut-driven appraisal and standardize ACV across dealers.

Term

historical data points

"looking at what is actually happening with our historical data points when we're putting numbers on cars."

Historical data points are past examples of what happened before. The idea is to use those past results to make better guesses about what a used car should cost today.

Concept

used car profitability

"We're just leaning into the data more so than we ever have been last year in terms of our used car profitability."

It means how much profit a dealership actually makes when it buys and sells used cars. If the price is off, the dealership can lose money even if sales volume looks fine.

Concept

used car acquisition

"so that's what led us to looking at how we're acquiring cars and looking at different partners... in 2026, used car acquisition has everything to do with the right price."

Used car acquisition is the process of sourcing and buying inventory from auctions, trade-ins, wholesalers, or other partners. The segment argues that in 2026 it depends heavily on getting the right price because profit margins are thin.

Concept

used car margins are so thin

"You've got to have enough data to make the right pricing decision... because the margins are so thin."

Thin margins means there isn’t much profit left after costs. So if the dealership pays or prices wrong, they can quickly lose money.

Concept

mispriced a car

"Was there an example pre this change where you mispriced a car? There was a trade miss. There was a customer conversation that went sideways because the number was less defensible..."

Mispricing means the dealership asks too much (or too little) compared to what the market will pay. If the price can’t be backed up with data, buyers lose confidence and deals fall apart.

Concept

inventory turn

"When we looked at how we were pricing our cars and our overall turn of our inventory, it was just we were hanging on to hope..."

Inventory turn is basically how fast the dealership sells its cars. If cars don’t sell quickly, the dealership has money tied up and has to deal with pricing pressure.

Concept

data-driven appraisal

"So being more proactive in the way we acquire our cars, price our cars so we can move them ... And what is retention plus VIN level data unlock that buying leads? ... when it comes time for us to offer them a value on their trade... they believe that we're going to be honest and fair and forthright."

They’re arguing that dealerships shouldn’t guess at prices. Instead, they should use data about customers and specific cars to price more fairly and consistently.

Company

Nilo company

"is definitely a better equation for the Nilo company and everybody in the industry at large."

They’re talking about a specific dealership group/company called Nilo. The point is that they’re trying to use better planning and data when buying and pricing cars.

Brand

BMW

"So I see a retention number from your BMW store, 74 percent. Tully's been on the show a lot."

The speaker mentions BMW because they’re using BMW dealership performance numbers as an example. Those numbers are used to show how trust and repeat service can influence other parts of the deal.

Term

retention

"So I see a retention number from your BMW store, 74 percent. ... So what is that 74 percent retention that BMW have to do with how you source cars today?"

In dealership terms, retention is the percentage of customers who return for repeat service and maintenance. The speaker frames retention as a measurable indicator of customer trust, which then affects how confidently the dealership can make trade-in value offers.

Term

VIN level data

"And what is retention plus VIN level data unlock that buying leads? ... just VIN level data, just unpacking the retention question, the 74 percent, you know, Tully does a great job..."

VIN level data means looking up information using a car’s unique VIN number. Since that number identifies the exact car, it can help the dealership understand what leads to follow and how to price more accurately.

Term

service department

"really tracking that number, holding the service department accountable and, you know, and he does that really by, you know, being competitive on maintenance items."

The service department is the dealership’s repair and maintenance shop. The idea here is that how well they handle maintenance affects whether customers come back.

Term

maintenance items

"being competitive on maintenance items. We're not here to make money on maintenance and tires and all that stuff."

Maintenance items are the regular upkeep and wear-and-tear parts a car needs over time. The speaker is saying competitive pricing on these helps customers trust the dealership.

Company

Nilo Volkswagen

"Dennis Gingrich goes down to Nilo Volkswagen and gets, you know, X and then literally goes around the corner and gets, yeah, it's a completely different number."

Nilo Volkswagen is a dealership used in the story to show that two nearby dealers can quote different prices for the same kind of vehicle. That inconsistency can damage trust.

Term

ACV

"Before we get to George and get to ACV, walk us through an acquisition story. Customer in your service drive, BMW, you've got their data, you've got VIN level pricing."

ACV is a way to estimate what the car is worth in today’s market. It’s the kind of number dealers try to calculate consistently when appraising used cars.

Term

VIN level pricing

"Customer in your service drive, BMW, you've got their data, you've got VIN level pricing. What's the conversation today versus what it would have been a couple of years ago?"

VIN level pricing is when a dealer uses the car’s unique ID number (the VIN) to price that exact vehicle. It helps avoid guessing based only on the model name.

Company

NADA

"out at a NADA and they, you know, they showed this project and it's like, it wasn't ready at the time,"

NADA is a reference guide dealers use to estimate what a used car is worth. It helps them put a starting number on a car before they consider the car’s condition and local market.

Topic

used car appraisal with data vs "art"

"George, Dennis described the problem that all of automotive faces today. Getting that great used car is job number one, ... Why is book data and segment pricing actually wrong, George?"

The hosts are talking about how dealers should price used cars using better data instead of guessing. The goal is to quote the right number for the exact car, not a rough estimate.

Concept

acquisition leads

"Sam, that the closing rate on these acquisition leads or, hey, we want to buy your car leads is very, very low, you know, and it's because it is sold to multiple dealers in the market."

Acquisition leads are people the dealership finds through ads or online marketing who could become customers. The idea is that it can take a long time to follow up and get them to say yes.

Term

closing rate

"Sam, that the closing rate on these acquisition leads or, hey, we want to buy your car leads is very, very low, you know, and it's because it is sold to multiple dealers in the market."

Closing rate is how often a salesperson turns a lead into an actual sale. If it’s low, it means many leads don’t end up buying or selling.

Term

DMS

"all the VIN level data and the metrics that are tie into our DMS to where we could really see what was going on."

DMS is the software system dealerships use to manage inventory and sales. If data is connected to the DMS, it can help the dealer quote and track cars more accurately.

Term

segment pricing

"Why is book data and segment pricing actually wrong, George? Not just imprecise, but wrong for the car that's sitting in front of a manager today in that lane looking to put a number on it?"

Segment pricing means pricing cars based on a category they fit into, not the exact car’s details. The episode’s claim is that category-based numbers can be off for the specific vehicle being appraised.

Term

book data

"Why is book data and segment pricing actually wrong, George? Not just imprecise, but wrong for the car that's sitting in front of a manager today in that lane looking to put a number on it?"

Book data is a published estimate of a car’s value from pricing guides. The point here is that the guide number may not match the exact car and its real local market.

Concept

machine learning and AI

"Sam, what we've done is we've predicted using machine learning and AI, we'd be able to predict the retail price of what the car is going to sell for in the next 30 days within $100."

They’re using computer models trained on lots of past car sales to guess what a car will be worth soon. The goal is to make the price estimate more consistent than relying on gut feel.

Term

trade in wholesale

"And we may be able to predict the trade in wholesale within $100."

When you trade in your car, the dealer has to buy it from you at a price that makes sense for their resale business. “Wholesale” is the lower, dealer-to-dealer kind of pricing, not the higher retail price you’d see on the lot.

Concept

digital dealer auction

"We have, you know, the largest dealer wholesale auction in the country, digital dealer auction, where we're inspecting over a million cars a year."

Instead of guessing, dealers can buy and sell cars through online auctions. Those auction prices help predict what similar cars should be worth.

Concept

franchise dealer

"if we don't allow consumers to trust the franchise dealer, they're not going to sell their car to the franchise dealer."

A franchise dealer is a dealership operating under a manufacturer’s franchise agreement, typically selling that brand’s vehicles and using brand-approved processes. The segment argues that if consumers don’t trust franchise-dealer pricing, they may avoid selling their car to that dealer.

Concept

democratize price

"And that ability to democratize price creates trust. And trust is important..."

The idea is that customers should be able to see a fair price without needing special insider knowledge. When the price is based on data, it’s easier for people to trust it.

Term

grab on attempted gross

"Or is it a grab on attempted gross, or is it just lack of experience?"

Dealers often have a target profit they want to make on a car deal. The speaker is saying some pricing differences might be driven by those profit goals instead of the car’s true market value.

Concept

pricing at scale

"Well, the big box guys aren't looking at, you know, what's the value of that car based on that one store. And so when you have the ability to price vehicles at scale, which we do, you now can predict what it's going to retail for in the next 30 days…"

It means the dealer group uses software to price lots of cars quickly and consistently. Instead of each store guessing, the system handles it for many cars at once.

Concept

predict what it's going to wholesale for in the next 30 days

"…predict what it's going to retail for in the next 30 days, what it's going to wholesale for in the next 30 days."

They’re also estimating what the car might bring if it’s sold through wholesale channels. Think “dealer-to-dealer/auction price,” not the retail sticker price.

Concept

predict what it's going to retail for in the next 30 days

"…you now can predict what it's going to retail for in the next 30 days, what it's going to wholesale for in the next 30 days."

They’re using data to guess what price the car will likely sell for soon. It’s not a one-time estimate—it’s a forecast for the next month.

Company

Viper

"…Dennis does explain George Viper in plain English to the dealer who's not used it. What's the workflow? What gets automated? What stays human? … So we had clear car. We have Max. Now comes Viper. Viper are two towers"

Viper is a software tool the hosts say helps dealers decide what parts of pricing can be automated and what still needs a person. It’s about the day-to-day workflow, not just the price number.

Company

ClearCar

"…clear car is the ability to be able to put a number on a car, whether it's a sell your car, trade your car… So clear car is powering the websites of… thousands of dealerships."

ClearCar is described as the product that assigns a numeric value to a vehicle across different contexts (sell/trade) and powers pricing on dealership websites. In this segment, it’s positioned as the foundation for condition-adjusted vehicle valuation.

Term

API

"…It's also the trade in for a large e-commerce company. It's the trade in. It's an API being used by two of the largest dealer groups in the country."

An API is like a digital “messenger” that lets different software talk to each other. Here, it means dealer systems can automatically use the pricing data.

Term

condition adjusted value

"…So clear car already gave us the ability to do a condition adjusted value. I believe it's starting to become the market leader in pricing cars to consumers."

Condition-adjusted value is a pricing approach that modifies a vehicle’s baseline market price based on its actual condition. Instead of treating every car as equal, the model accounts for differences like wear, damage, and overall condition.

Company

Max

"Then there was Max. Max is the sister product. Max does the retail prediction, wholesale prediction, inventory management…"

Max is another software product that helps predict what a car should sell for and manage dealer inventory. The key idea here is that it can update prices automatically.

Concept

automatically doing, setting retail prices and changing them every couple of days

"Max does the retail prediction, wholesale prediction, inventory management and even go as far as automatically doing, setting retail prices and changing them every couple of days."

This is dynamic pricing: the system updates retail prices automatically as market conditions and inventory signals change. Changing prices every few days helps dealers stay competitive without relying solely on manual repricing decisions.

Term

undercarriage

"scan the undercarriage called virtual lift... take the entire vehicle, know whether or not there's a dent... whether or not there's something with the undercarriage"

The undercarriage is the bottom of the car—where you’d see things like the suspension and the parts that can get hit by potholes or debris. Its condition can strongly affect whether a used car is priced as “clean” or not.

Term

virtual lift

"coupled with our scanner to scan the undercarriage called virtual lift. You drive through and it leverages video"

“Virtual lift” is a way to check the bottom of a car while it’s still on the ground. It helps the system spot damage or issues that would normally require lifting the car.

Brand

Carvon

"CarMax, Carvon and others would love."

The host mentions another used-car company besides CarMax. The exact brand name in the transcript is a bit unclear, but it’s being used as an example of a buyer that wants “clean” cars.

Term

CRM

"We're pumping it back into the CRM. And now it's up to the dealer to follow up"

CRM is a dealer’s computer system for managing leads and follow-ups. Here, the scan results get stored there so the team knows what to do next.

Concept

follow up on day one, week two, day 60, day 90

"we have to follow up on day one, we have to follow up on week two, we need to follow up on day 60, we need to follow up on day 90."

They’re using a schedule for contacting leads multiple times. The point is to keep following up—right after the car is scanned and then again weeks later—so more leads turn into sales.

Concept

capturing the data

"But it's all about capturing the data, pumping it back into your CRM, having an established process and follow up"

The big idea is that pricing used cars should be based on real condition information. They’re describing a process where the scan results are recorded and then acted on consistently.

Concept

service drive

"what we signed up as free leads out of the service drive... Those are absolutely the best cars we can have in our inventory"

The service drive is where cars go for maintenance and repairs. The hosts are saying cars that just went through service are often the best candidates for inventory because they’re more likely to have been cared for.

Term

tumble leads

"When they run through the system, we don't have to worry about our sales manager that's too busy counting tumble leads"

“Tumble leads” sounds like a term for leads that aren’t very promising. The speaker is saying the service-drive cars are better leads than the usual lower-quality ones.

Term

curb rash

"check tires, check brakes, check for door dings, check for curb rash, matching tires and all those things."

Curb rash is scuffing or scraping damage on a wheel from hitting the curb. It’s important because it can mean extra repair cost and can lower what the car is worth.

Term

matching tires

"check for door dings, check for curb rash, matching tires and all those things."

Matching tires means the tires are the same type and tread level. Dealers look for this because different tires can be a safety/quality concern and may require replacement to sell the car properly.

Term

door dings

"check tires, check brakes, check for door dings, check for curb rash, matching tires and all those things."

Door dings are small dents from someone bumping your car door. They matter because fixing them can cost money and can lower the car’s resale price.

Car

Volkswagen Id4

"...y on the brands we represent, I have a Volkswagen ID4, I commute back and forth. I had to buy a new tir..."

The Volkswagen ID.4 is an electric SUV, which means it runs on a battery instead of gasoline. It’s made for regular driving like commuting, and you charge it by plugging it in. Because it’s electric, some parts wear differently than on gas cars, and owners may notice things like tire wear from everyday driving.

Part

cat converter

"This was pre-ACV Max. We took a car in on trade, went through the shop, long story short, cat converter was gone. We missed it."

A catalytic converter is a part that cleans up car exhaust. If it’s gone, the car may fail emissions checks and it can be an expensive problem to fix—so it needs to be caught during inspection.

Term

flagged

"and the amazing picture it generates is like, Houston, we have a problem. And that is where I think the manager comes in. When these things are flagged, it's like, hey, hey, we really need you to come and look at this thing"

“Flagged” means the computer system is warning that something might be wrong with a car. The manager then checks it in person to confirm before making a pricing or buying decision.

Term

AI tools

"instead of chasing things all over the worldwide web with 12 different AI tools that say 12 different things."

“AI tools” are computer programs that try to help dealers make decisions about cars. The host is saying different tools can disagree, so you still need a solid process and people to verify what’s going on.

Term

inventory management

"Everywhere a used car or used piece of inventory touches the dealership ecosphere, you're owning that... end to end when it comes to used cars, inventory management. It's a Swiss Army knife to get the job done."

Inventory management is how a dealership keeps track of cars—what they have, what it’s worth, and what stage it’s in. Here, they’re saying the tool helps manage that whole process, not just a spreadsheet.

Term

trade process

"You're owning the entire ecosphere. You're owning the inventory management, you're owning the trade process in the service department, the used car trading process in used cars..."

The trade process is what happens when you bring in your current car as part of buying a different one. The dealership has to figure out what your car is worth and what to do with it next.

Term

ecosystem

"What hits me that this is different... is you're owning the entire ecosphere. You're owning the inventory management, you're owning the trade process..."

Here, “ecosystem” means the whole chain of dealership steps that involve a used car. They’re saying the tool connects to many parts of that chain, not just one step.

Term

auction acquisition

"even the auction acquisition process. Everywhere a used car or used piece of inventory touches the dealership ecosphere..."

Auction acquisition means buying cars from auction sites (usually wholesale). The idea is that the same data-driven system helps decide what to buy and how to price it afterward.

Term

workflow solution

"Matter of fact, I think just inventory management to be a workflow solution will be nearly dead in the next handful of years. We can't just think about workflow like screen A, screen B."

A workflow solution is like a guided checklist app. They’re saying that in the near future, tools that only guide steps won’t be enough—dealers will want the data to connect directly to their main systems.

Term

core actual cash value

"We've got to go out there and integrate. And so we're determined to really be that core actual cash value. We're not trying to be every vendor."

They’re talking about a “real” value number for the car—what it should be worth in cash terms. The point is that their system is built around producing that valuation, not just being another app.

Concept

data science predictions

"Here's the data science. Here's where we predict in the next 30 days it's going to retail for."

They’re using software models to predict what a car will be worth soon, instead of relying on gut feel. Those predictions help dealers decide what to offer and list the car for.

Term

VIN specific pricing

"it's your focus on VIN specific pricing, right? You're not bundling, you're going VIN specific."

VIN-specific pricing means the quote is based on the exact car you’re dealing with, not just the model name. The VIN is like the car’s unique ID number.

Brand

Carvana

"all these customers, whether they're going to Carvana, CarMax or the Nilo company or wherever, when they get a value on"

Carvana is a company that buys and sells used cars, often online. They’re mentioned as one of the places customers might get a value from.

Term

pricing intelligence

"So George, why did ACV decide to build the pricing intelligence around the VIN and not just the segment or make model..."

Pricing intelligence is basically “smart pricing” using lots of data. Instead of guessing, it tries to estimate a car’s value using details about that specific vehicle.

Term

banded

"it's the old banded thing we used to do as Zurich Dennis, right? You're a VIN specific, you're not banded."

“Banded” means putting cars into rough groups and pricing them from the group average. The point here is that VIN-specific pricing is more precise than those broad buckets.

Term

wholesale side

"before we were pricing retail cars, right, we already saw that data on the wholesale side."

The “wholesale side” refers to pricing and transactions between dealers (or dealer networks) rather than retail sales to end customers. The speaker claims the system already saw condition-adjusted data there before expanding into retail pricing.

Term

no reserve

"keep in mind, you know, over 20% of the cars running on ACV right now are no reserve."

No reserve means the seller isn’t setting a minimum “must get at least this much” price. If bids don’t reach a certain level, the car can still sell—so pricing accuracy matters a lot.

Concept

common issues with a year make model brand

"So I think about there. There's a big competitor in the space that recently [1799.5s] is saying, Hey, we're working on the capability to bring in common issues with a year make model [1804.2s] brand."

The phrase describes a valuation approach that accounts for recurring problems tied to specific vehicle attributes like year, make, model, and brand. Instead of treating every car as unique, the system tries to learn which defects are common for a given configuration and adjust value accordingly.

Term

artificial intelligence

"And you know, the breakthroughs of what you can do now, [1871.6s] leveraging artificial intelligence, I think we had the vision of where it was going to go."

Artificial intelligence is computer software that learns from lots of examples. In this context, it helps estimate used-car value by learning patterns from vehicle data.

Concept

inflection point

"But it took us a few years. And I think in the world of technology, it's hard to predict like [1883.4s] when you're going to be done. But I think we've hit an inflection point this year that's very [1888.6s] significant."

An inflection point is a turning point where things start improving faster or working better. Here, it means their valuation product reached a stage where it started delivering better results.

Term

retail pricing

"we're automating the retail pricing with someone else that was on your show and automating the retail pricing all the way down where you don't even need to actually change the prices and it automates the descriptions."

Retail pricing is the customer-facing price a dealer puts on a used car for sale. Here, the system can automate those prices and related listing details.

Term

guardrails

"I mean, there are guardrails that will help prevent, keep a dealer confident that it's not going to start dropping prices irrationally, right?"

Guardrails are safety limits that stop an automated pricing system from making extreme or unreasonable price changes. The idea is to keep pricing consistent even when the market shifts fast.

Term

AI-powered pricing

"Thinking about where you're taking the product next and what the AI-powered pricing landscape looks like, what do you have ahead, George?"

AI-powered pricing means using software that uses data to help set car prices. The hosts say it can automate pricing and descriptions, but with rules to keep it from making wild changes.

Term

aftermarket

"they literally had an entire undercarriage of the BMW that was all aftermarket undercarriage."

Aftermarket means the parts weren’t made by the car’s original manufacturer. The hosts are implying that non-factory work on the underside can be a risk worth investigating.

Topic

dealer adoption curve

"So, George, talk to us about the dealer adoption curve. What separates those dealers who embrace"

This phrase means how dealerships gradually start using a new system or service. They’re about to explain what makes some dealers adopt it faster than others.

Concept

automated processes to buy cars

"So, no longer is this saying, trust that this will happen in the future. So, dealers that are adopting, you know, automated processes to buy cars are buying more vehicles."

They mean using computer systems to handle the used-car buying steps instead of doing everything by hand. That can make the process faster and more consistent.

Term

trust

"that's really the core of this whole thing is your brand matters, trust matters."

They’re talking about whether customers believe the dealership is being honest and consistent. If prices don’t line up, customers may not trust the process.

Term

GSM

"So, Dennis, what advice would you give to a GSM who's hesitant to make a change like this, to how they've always priced cars?"

GSM usually means General Sales Manager. It’s the person in charge of how the dealership runs its sales process, including pricing decisions.

Concept

data-driven pricing vs gut-driven pricing

"so much of pricing and automotive five years ago, even maybe even two years ago was so much gut driven. And that used car manager was an artist... Man, you just got to go to the data."

They’re comparing pricing based on intuition (“gut”) versus pricing based on data. The point is that data can back up the decision instead of relying on one person’s instincts.

Concept

use car manager

"“Once you get over the curve, right? Once you calm that use car manager down...”"

A used-car manager runs the used-car side of the dealership. The point here is that once the data tools are in place, the manager spends less time guessing and more time helping customers.

Concept

AI vendor

"“...if you've got an AI vendor going out and be able to message consumers and following up...”"

An AI vendor is a company that uses software (AI) to help dealers contact customers and keep up with follow-ups. It’s meant to make the process faster and more consistent.

Term

BDC

"“...we could just integrate this into your BDC right now and just have a great process.”"

BDC is the dealership team/system that handles leads—calling and messaging people after they show interest. The goal is to follow up quickly so you don’t lose the customer.

Term

VIN captured

"“...we coach you because we all know getting the VIN captured is step one. The follow up really important.”"

The VIN is like a car’s fingerprint. “VIN captured” means the dealer gets that number so they can look up the exact car and price it correctly.
