Keeping your car roadworthy without the guesswork
Keeping on top of car servicing and MOT work helps you avoid bigger repair bills later, and it gives you a clearer picture of how your vehicle is really performing. We carry out servicing, MOT testing, MOT preparation, diagnostics and general repairs for most makes and models at John Cox & Son Motor Engineers Ltd in Chesham Bois. That means if your car feels sluggish, shows a warning light, or simply needs its annual check, we can sort it properly and explain what we find in plain English.
Our family-run garage has been working on local vehicles since 1970, so we've seen the sort of wear that comes from school runs, short trips and daily commuting. Preventative checks can pick up issues like tired brakes, worn tyres or battery trouble before they leave you stranded at the side of the road. You get honest advice, practical maintenance and work that helps you drive away with more confidence.

A proper look at what your vehicle needs
Our diagnostic work helps track down faults that aren't always obvious during everyday driving, especially when dashboard lights appear with no clear cause. We also prepare cars for MOT tests by checking the areas most likely to cause problems, which can save you time and repeat visits.
Engine repairs and routine maintenance are handled with the same straight-talking approach, so you know what needs doing now and what can wait. We work with motorists from Chesham Bois and nearby communities who want sensible answers instead of confusing jargon. It's the sort of garage service that keeps things simple, fair and easy to follow.
"Excellent garage, excellent mechanics, I’ve used them on numerous occasions and they are always very honest. Today I visited them with a problem to do with my clutch which I thought had gone (all resistance in the clutch had gone and I couldn’t change gears), one of the mechanics took a look at it and within minutes had fixed me back up - and he didn’t charge me a thing. Bearing in mind there are lots of garages who will over charge you for things like this, especially as I know very little about cars, I was very impressed. Can’t praise them enough."
