If it's as good in person as in pics, my advice would be- buy it!!!!! I've seen a lot rougher ones go for more around here!
Glad you are catching it before paint so you can see all its issues- if PO was stripping stuff off for paint without having done any rust repair, I'd wager he was thinking about doing some sketchy patch jobs just to get it to look okay with new paint rather than real repairs! Funny sketchy body "repair" I've seen recently was crushed cans of Busch used as a backing for bondo in rusted out rockers, LOL! (seen plenty of newspaper and screen but never crushed beer cans)[/QU
