Keep your car running without the guesswork
Car servicing and MOT work should leave you clear about what your vehicle needs and what can wait. We carry out servicing, MOT testing, MOT preparation, diagnostics and repairs for most makes and models, helping you stay safe on the road and avoid small faults turning into costly trouble. At John Cox & Son Motor Engineers Ltd, we've been helping drivers in Latimer since 1970, and we still believe plain speaking matters.
If a warning light comes on, your brakes feel different, or your car just doesn't sound right, we'll inspect it properly and explain what we've found in simple terms. Our routine maintenance and preventative checks can pick up wear before it causes a breakdown or a failed test. That means you can make informed decisions about your car in Latimer without feeling talked at.

Practical garage support for everyday motoring
From MOT preparation to engine repairs, we focus on the jobs that keep your vehicle dependable day after day. Our diagnostics help track down faults that aren't always obvious, which is especially useful when a dashboard light appears, but the cause is unclear. Preventative checks can spot worn parts before a long journey, a school run, or a daily commute turns into a roadside problem.
We work on general repairs and ongoing maintenance with the same steady approach, giving you honest advice about what needs attention now. You'll find us easy to talk to because we know most people want straight answers rather than garage jargon.
"The crew from Amersham Auction Rooms have been using John Cox for almost 15 years now and we wouldn't go anywhere else. They are so professional, and you will always get good advise.......even if you don't like the news. Example ....my car needed a new alternator and it was running a little rough, I took their advice and I've been driving it trouble free for two years now. They are the most honest garage you will come across."
