Kevin and Roy are superb mechanics and never cutting corners when it comes to safety. Kevin is always spot on the diagnostics. Roy’s inspections and work is always above and beyond.

You saved my day and probably my job! 🙂 I had actually called 3 other repair shops and their main concern was closing down their offices at the end of a busy day ( and I'm not blaming them ). 1st you helped me over the phone to get to your location and then got me back on the road and running as if I hadn't even missed a beat. I was able to still pick up my load and will still make delivery on time. Cant say thank you enough. Thank you thank you thank you!! Hail to the Redskins... but you Cowboy fans earned my respect and gratitude today. " God, you showed me again today we still have good people here.
