I have been getting the expertise done for my cars regularly without having to do any special mechanical work since the service etc is regular. I do ofcourse clean the car and the engine bay thoroghly myself.
In my experience it depends very much on where you take it and the person inspecting. Brakes and lights are the big things for sure but any sign of rust and could be trouble. Good luck in any case.
And at least in BS, they ride it *hard* around the lot. Rolling on the throttle quick, doing sharp weaves and turns (checking suspension) and then some hard braking.
I’m forbidden from making noises on Sundays, but others are welcomed to roar around our village, reaving their engines, and that’s OK. Yes some jerks do the same in their cars, but there is no reason why we should not regulate the noise.
