“I had a series of truly terrible issues with a new-to-me truck and failed rebuilt engine (rebuilt elsewhere). Upon professional advice, I had my truck towed to Supertech. They gave me superb service and went over and above navigating warranties and getting my truck fixed and running. I highly recommend Supertech. Their work and customer service is exceptional.”
