Wish you had posted this before the auction ended. NY is a long haul but I may have taken a run at it for what it sold for.
I would attempt to save the roof. With 6-7 porta powers, patience and a heat gun, I believe about 90% of that would come back. I don't see but a few creases deep enough to stretch. Paintless dent removal to the extreme...
Yes, it would need final filler and paint, but so would a replacement.
I'm, also, going to put, at least, a 50% chance that this will be back up for sale shortly with some improper and crude roof repair and a few other "improvements" for about 20k...
