My dump truck blew a tire and tore an airline off. They not only got me new tire installed, they fixed the airline very quickly and at an extremely reasonable rate. I am about 45 minutes away from their shop. However, I’ve decided it will definitely be worth the drive for Rick’s level of care when it comes to getting things done and done right. Bonus, he was fun to shoot the breeze with!!

Rick took our call on a Sunday afternoon (his shop was closed but he still offered to help us) after we accidentally misfueled our car, saving us from a $1,400 tow back home. He was professional, kind, and had us back on the road much sooner than we expected. If you need honest, reliable service, go see Rick.
