I have to say first that I’ve not had a very good experience with GM dealerships in general, but this time I decided to give Parker- McGill a shot and... I am SO glad that I did. The service managers both were very helpful and knowledgeable. I felt as though I was the only customer that they had, which I know wasn’t true because the shop was full. It’s two days before we leave for our beach vacation and our AC quits so you know what that trip would be like...the service department got us going the same day and I can’t thank them enough. I will use them again without hesitation.
