About this episode

Brown March bounces between small-engine tinkering and classic-car auction talk, with plenty of banter in between. The hosts troubleshoot a two-stroke petrol strimmer that wouldn’t restart after years, then explain why it fired instantly once set to full chogun. Later, they run a “pick a car” segment, landing on a 1986 Mercedes-Benz 300 SL and discussing R107-era details, documentation, and convertible rust-prone areas. The episode also covers real-world ownership issues on a Mk7 Golf and winter lubrication advice.

Car

Mercedes SL

"because I brought up the Mercedes SL and how I feel like the SL has just sort of somehow lost its magic and you don't really see them around anymore,"

“SL” is Mercedes’ roadster line—cars meant to feel sporty and upscale, often with a soft top. The host is basically saying that, in their view, the SL doesn’t feel as exciting or special as it used to. That sets up why they’re talking about a specific SL example from the past.

"And this week, Johnny, I have picked for you a 1986 Mercedes-Benz 300 SL, the classic,"

The Mercedes-Benz 300 SL is a famous Mercedes roadster/GT name. When the host says “1986 Mercedes-Benz 300 SL,” they’re talking about a later SL-era version of that model line, not the earliest legendary 300 SL from the 1950s.

Term

soft top

"It's got a new soft top. It's also got the color-matched hard top."

A soft top is the fabric convertible roof used on many roadsters. Replacing it matters because it affects weather sealing, insulation, and how the car looks and feels day-to-day.

Term

Term

fuel flap

"actually, can you help me with a problem? Can't get the fuel flap open on my Golf?"

The “fuel flap” is the hinged door that covers the vehicle’s fuel filler opening. If it won’t open, it’s usually a latch/actuator or release-mechanism issue rather than anything to do with the engine itself.

Term

actuator

"And there's a little sort of actuator thing that rotates to lock the flap shut, and it just sticks or breaks, and that's it, and you can't..."

An actuator is a small moving part that does the “push/pull” action for a mechanism. If it jams or fails, the flap won’t open properly.

In the UK, an MOT is a regular safety check your car has to pass to be allowed on the road. The host is saying the car was due for that check soon, so the repair could be bundled in.

Term

solenoid release

"And I don't like anything that's a solenoid release, which is so crucial, because you're relying on one component that will either make or break the interaction."

A solenoid release is an electrically controlled latch. When you press the button, it uses electricity to trigger the latch—so if that part fails, the door won’t open reliably.

Term

boot release is a solenoid

"Obviously, the door handles are pure mechanical. Boot release is a solenoid, and they always fail."

Here they’re saying the trunk/boot lid opens using an electric latch (a solenoid). If that electric latch breaks, you can’t open the boot normally.

Term

electronic handbrake

"the first Renault Scenic that had an electronic handbrake, so sort of two generations ago, maybe. Yeah. They used to fail and jam on."

Instead of a cable you pull with your hand, an electronic handbrake uses a motor to clamp and release the brakes. If it malfunctions, it can get stuck and won’t let the car move normally.
