I wanted to put in a good word for Bob Bell Chevy in Bel Air, MD. I've had nothing but positive experiences there.
I took the car in to document rub marks on the convertible top and ended up with a replacement. The trim shop didn't do it right, so they made sure to fix it right there and let me watch. There were little metal filings in my seat creases and window tracks, so they got all of that taken care of too. The trim shop dinged the edge of the trunk...no problem, when can we fix that for you? It was done perfectly.
I got a free oil change because I had to wait "an unusually long time."
Someone took a chunk out of the paint on my rear panel, they fixed it up right.
I highly recommend them.
