I am giving Premium 5 stars not because they are perfect but because they are honest and have integrity which is hard to find and very important to me. I brought my truck in with a check engine light. I had pulled the codes and it was related to the evap system. They did their diagnostics and made a determination. The day after I got the truck back the same codes popped up. I called them, took the truck back, and they fixed the issue and made things right. They are professional and customer oriented.
