Sure looks like there's a lot of Bondo in that right rear quarter, and a rust hole to boot. Someone out there is crazier than I am or they know something about the car that makes it special, I have no idea what that could be though.
There's absolutely no way that is a good candidate for a restoration. Sitting in a garage for more than 20 years wrecked is bad enough but there is absolutely nothing salvageable about the whole front end or the right quarter. Where would you even begin to locate the myriad of decommissioned parts for it? I guess since it still has a seat in it there will be a butt to fill it.
From the photos the radiator is collapsed in two directions, the entire front suspension and steering assembly is wiped out, all the sheet metal is gone, its likely that the cooling fan is laid up on the water pump inside the engine bay too. The windshield is broken, no doubt the driveshaft got slammed into the transmission casing in the crash. Congrats to the seller and good luck to the lunatic *ahem* buyer who dropped cash on this.
