I brought my car to One Stop Autos after it developed an unusual electrical fault. Marty went above and beyond to both diagnose and fix the issue. I found him to be genuine and honest and would have no hesitation in recommending him to family and friends. If you want your vehicle to be looked after by someone you can trust, you'll be in safe hands with Marty.

I needed a mph fascia for a speedometer on a car I was importing. Marty couldn't have been more helpful and got the work done so quickly and provided all the documentation I needed to get the Conversion cert to register the car with the DVLA.
