“I am new to the area so I was skeptical about finding a decent mechanic. After dealing with Gary's auto service I can say that I have found my new hometown mechanic that exceeds the standards. Very personal, professional and trustworthy. They gave me a detailed description of what was needed for my car without the pressure or any sort of deception. Savannah was very friendly as well. To top it off, they dropped me off at home after I left my car with them and then picked me up when it was ready. If I could rate more than 5 stars I would!” -- Corey B.
