Looks like a long term inmate of body shop prison. If nothing else, a lot of great parts for the money. Best part is, the hood is on it's side! https://memphis.craigslist.org/cto/d/memphis-1970-buick-gs350-project-car/7681959478.html
That shouldn't last much longer than it'd take me to drive there. Unfortunately a bit too far away to go grab.
I bought that same car color combination back in the 80s in one piece in better condition with two rods hanging out the original block for 50 bucks.
But you could put some lights on it for the holidays. seriously though, seems like a deal for the sheet metal.
It appears to have either been acid dipped or blasted, then left bare and rusted again. It has to be re-dipped or blasted again, now. Unless you're looking for a parts car, I would pass on it.
