Customer Reviews

Jeff Patterson

Had brakes repaired on my 2012 Expedition. Completely satisfied. Owner is honest and makes a great effort to see that each repair is to done correctly and that the customer is satisfied. Brant Jones has been my mechanic for 18 years. An honest and helpful mechanic is a good find. Any one star reviews are most likely written by someone who cannot be pleased or by a competing auto repair shop.

Absolutely fantastic! I work for a roadside assistance company and I called then to help us with a tow the other night, Blue was amazing. He got there quickly and was super pleasant on the phone. If I can even get more business their way they will get it every time. #teamblue

Lou was friendly and informative when he towed my vehicle. The repairs done to my vehicle were fast and inexpensive and the women at the front desk was great. Cannot recommend these people enough.
