Sounds like it needs quite a bit of work and there are too many potential unknowns. As a professional body guy a word of warning about cars that are "in primer and ready to paint" they never ever are, primer hides sooo much, from poor quality body work, improper prep, small dings, untreated rust, etc... Looks like the car was primed right there in the woods, definatly as far from doing it right aas possible. Id pass and find a more sorted car.
