They're my go to repair shop now!

Customer Review
★★★★★
These guys are the best! I took my truck in for a heater core. They did the work and the truck smelled like coolant bad and after the heater core replacement my thermostat was not working right. They had me bring it back and ended up doing a coolant flush and replacing the thermostat with no extra charge to me. I can't tell you how thankful I am that they did this after paying over $760 for the heater core! Really awesome guys and gals over there! They're my go-to repair shop now for sure!

Great.

Great shop. - Jo Ann M. (5 star review on Google)

Phenomenal crew!

These guys are phenomenal! Had them install a transfer case for me and an electrical clip break off after I left their shop. I went back and they found the problem and fixed it right away! Keep it up y'all! - Kevin J. (5 star review on Google)

Quality work!

Fair and quick! Quality work and friendly! I bring my personal and fleet vehicles to My Master Mechanic and have no reason to look elsewhere! I’m very happy! - David S. (recommended on Facebook)
