I believe I stumbled upon a '68 or '69 Belvedere...

Regardless of what you end up doing with it, I can see over $200 worth of parts. Heck the dash actually doesn't look bad. That could be deceiving in the pics though. But with it sitting on the ground like that the frames rails are likely toast. Offer him $100 and drag it out of there. What's he going to do with it anyway? Obviously not a lot!
