The bumper on the grey car has been replaced, but there's no damage behind it, looks like it was a light hit.
The CompG is un-fixable with a salvage title. It has major unibody damage. It was hit so hard that the body twisted enough to pop the sunroof up and buckle the opposite side rear quarter. The guy I bought it from was a body guy that bought it to repair, and he agreed that it wasn't worth it at all.
I'll probably just pull the Diff out of the CompG trans and toss it in the GT then.
