NIRMAL KT2025-06-24Trustindex verifies that the original source of the review is Google. I went to Mairtin with a few electrical issues on my volvo v40, and I have to say—he’s a really trustworthy and honest guy. He took the time to explain everything clearly, including what had been done and what could be looked at in the future. I'm really happy with the service and the way everything was handled. It’s rare to find a garage where you feel you’re not being ripped off. Highly recommend this place to anyone who just wants to get the job done properly and fairly. Will definitely be back if I need anything else! Rick McKee2025-05-29Trustindex verifies that the original source of the review is Google.

A great job done on the motor, highly recommend jack finlay2025-03-04Trustindex verifies that the original source of the review is Google. Recently contacted Marty about maintaince and repair of our fleet of 26 vans after having problems with our previous mechanic. Could not recommend him enough from the first phone call to the first booking he makes looking after a big fleet less stressful . No job to big or small for him we have had multiple vans around with him for repairs and servicing work. He keeps me informed on what it needs is very honest and doesn't try to rip you off like most dealers do. Has a fast turnaround to keep our vans out working. All at a very competitive price and the highest of standards. I recommend any business who has a fleet use One Stop Autos the best in the business.

My work van wouldn’t start, problems were worse than we thought but couldn’t get the van towed due to tight driveway. This guy worked at it all day and wouldn’t be beat… it was -2 degrees all day and the guy got me and my small business up and running again. Nothing was too much trouble, really nice guy. Can’t recommend him enough. Thanks Marty!! Stuart Newstead2025-01-08Trustindex verifies that the original source of the review is Google. Martin was professional and clearly knows what he's doing.
