Thanks for the replies.

nobody can argue with that.
Exactly what I was thinking. It was hard not to laugh when they showed me the "damage".

As far as I know, the differential is fine and there is no damage that I know of beside the bolt. Once I saw the differential angle I immediately called roadside assistance even though the car was actually driveable. I think they are grasping at straws -- "oh we deny the claim based on that scratch on the fuel tank, well, we better put in that the entire fuel tank has to be replaced then." Does anyone know how thick the plastic of the fuel tank is? The scratch is probably less than 1/16" deep.

Two reasons I am preparing to stand and fight with the dealer: 1) I was actually preparing to sell the car before this happened. I think this car is special and mine is a particularly mint example. I want to make sure the repair is conducted 100% properly so there are no issues for the next owner. 2) I feel wronged by the dealer (of which I was a loyal customer) in this case; so it's become a bit of a personal mission for me at this point.

As far as I know the car has never been on a jack except at this particular dealer and is always parked in a secure garage.
