Adam, If you really want to know, Buy it. Haul it home and park it next to the 58!!! Just jerking you man.
It is hard to say from the pics, but I agree that it looks like it has a lot of rust. Looks like it was sitting under a tree with the top down for a long while.
This one has been on Craigslist for the better part of a year now. He hasn't gotten the hint and dropped the price. Good idea to let this one go
These things tend to rot in the floors and the rear body mounts. At the price he's asking, it needs too much work, - I'd let it go. However, it would make a nice parts car for mine...
