Of course I can do it. I spent the better part of my formative years doing bodywork on old British cars. That's not the point. The point is that even with a background in autobody repair you can't tell everything from a few crappy pictures. If you can see problems, then there's problems. If you can't, it doesn't necessarily mean there aren't any problems, it just means that you can't see them. Maybe it's the lighting, maybe it's the angle of the picture, maybe it's the quality and size of the picture. The Demon in question has the potential to be a total disaster. You asked why it hadn't sold, that's the answer. It doesn't even look good on the surface, and the combination of tiny pictures, terrible lighting, and cheap primer blanketing absolutely everything means what you can see is only the tip of the iceberg.
Whoever bought that car has their work cut out for them. Hopefully they saw it coming, and negotiated a better price. Demons are hard to find, that one is still worth fixing, it's just the cost and knowing what you're getting into.
Well, the front isn't screwed. It is missing the grille in that picture but I removed it, and the valance is definitely kinda beat up, too many parking block encounters. But yeah, compared to what you can't see, that's nothing. That Challenger as is sits in that picture needs new quarters, half the floor, half the trunk, most of the rear frame rails, part of the firewall, parts of the kick boxes, and about half of the hardtop structure replaced. It's a flaming disaster.
