Well, to their credit, I have not not had any really bad experiences with them. We've had a couple of items we didn't quite see eye to eye on, but overall I'd give them passing grades. It's more of an inconvenience thing and a cost thing and a feeling on my part that I will give the car more loving care.
I took the car to them a few times when it was under warranty, but other than that, I'd rather do it myself.
