Keeping your car roadworthy without the guesswork
Car servicing and MOT work should leave you clear on what your vehicle needs and what it can wait for. We carry out servicing, MOT testing, MOT preparation, diagnostics and repairs for most makes and models, with straight answers that help you make the right call. A small warning light can point to anything from a sensor fault to a bigger engine issue, so getting it checked early often saves hassle later.
At John Cox & Son Motor Engineers Ltd, we've been helping drivers in Chesham since 1970, and we still believe honest advice matters just as much as the repair itself. Our preventative checks help spot wear before it turns into a breakdown or an MOT failure. That means you can drive around Chesham with a bit more confidence and a lot less second-guessing.

Practical garage support for everyday motoring
Routine maintenance is what keeps the bigger bills from sneaking up on you. We look at the condition of key parts, prepare vehicles for test day, and investigate faults with proper diagnostic checks instead of guesswork. If your car is due an MOT, feels rough on the road, or starts making a noise that wasn't there last week, we can get to the bottom of it. Our mechanics handle general repairs and engine work with the same clear approach we use on servicing. We keep things simple, so you know what needs doing and why.
"Very good garage. Proper 3 generation family business with expertise across all ages and makes of cars."
