I've been here twice for smog checks. The person on the phone was professional, pleasant, and got me in right away. I was there only about 15 minutes and they were finished! What impressed me the most, though, was listening to the clientelle they have. Both men who were either dropping off or picking up a car at this auto shop were VERY knowledgeable about cars, and they were bringing their car here to be fixed! Says a lot about the expertise of the people who work on cars there. I'll be back, for sure, with another car to see if they can determine the cause of a problem a private mechanic and the GMC dealership haven't been able to figure out. Great customer service, great expertise.
