I have taken my son's car to Cort Auto Body a couple times. They're efficient, responsive, and the ladies in the office are always very friendly and responsive. The guy that did our estimate worked with us on getting what we want. He was not real friendly, but he was efficient.
The only complaint I have, and it's not one that makes me angry, is that they were giving us dates about when they would be done, and as of last Thursday they said they were still targeting a Friday completion.
Since it didn't get done until Tuesday, I think they could improve upon setting expectations on when the car will be completed. I know there are things that come up like waiting on parts, but that's part of their business and how things get done.
