Yeah this one isn't great, but I think we're losing vision on this one. And I can't believe we're talking that it should be parted out.
It's a 300, it's a vert, it has the TNT, buckets/console, and it has awesome colors. If I didn't know what this car was I'd think we were discussing a 383-2 Newport coupe. This car is surely 1 of 100 or less?
I think the biggest questions, which I haven't seen answers for, are is the engine seized, how much unseen rust does it have in the framerails and windshield frame/cowl, is the top-frame OK, and how is the dashboard/electrics due to the outdoors exposure?
All the body lines look straight to me, that's a good sign. And it's no longer a virgin-metal car, so a different approach is needed. You simply don't do a 'full' restoration on this car as it will never be suitable for that. You fab up the trunk floor/extensions and quarterpanel patches from 16 ga sheetmetal. Maybe get floorpans from a 4dr and splice in as needed. It would be a lot of work but not terribly expensive (I've fixed quarters worse than this car). Fix it up with a cheap paintjob to be more presentable and enjoy it for a few years.
As far as the interior and the rest of it, perhaps it's not much different than any other project 'vert might need?
Yes, a lot of work, but if a guy could do it himself it has potential to be drivable and enjoyable again.
