Time after time they have proven to be 100% trustworthy. On my most recent visit, all that needed to be done was reset my car's engine service light. I was expecting a major repair and large bill. Instead, after completing the diagnostics, they reset the sensors, checked all of the fluids & belts and then presented me with a bill of $0.00! I have always found them to be efficient and very reasonably priced as have the other customers that recommended them to me.
