This happened to us at a muffler shop in Tucson, AZ. We were having code issues and the dealership said we had an exhaust leak. Turned out to be the Halltech intake but that's another story. When we returned to check the exhaust work we noticed the idiots didn't know how to lift a Vette. We have pucks now!! The worst part was the fact that we went through our own insurance company and asked them to go after the muffler shop. It went through arbitration and they decided we didn't have a case even with a bunch of pics of it still on the lift. The paint was scuffed and dirty but it wasn't cracked.
