Gmc service near Rockville, MD

Had been going to this guy for 15 years. In April 2014 Took my car in, guy kept if first 2 weeks, didn't address the problem. Afterwards I had to return the vehicle 6 times and he still didn't repair the problem. Took the car to the dealer who found the problem and said GAC had installed a cheap aftermarket part (not OEM) that was incompatible with the vehicle that doesn't take aftermarket parts. This guy ripped me off and refuses to reimburse me. Also I asked from the beginning for the parts he replaced, he lied saying I never asked for the parts. He did the same thing to my daughter. I would never take my car back to this guy after the way he ripped me off.

Bethesda Sunoco and the whole team, Ian, Don, Mike, Dominic are terrific. My friend had a car that did not pass emissions inspection. She took her car there and Dominic looked at the car and told her exactly what was wrong and what it would cost. She offered to pay him and he declined. I can see why they have such a high Washington Checkbook rating! Hard to find honest mechanics!
