I drove my 78 Home from New Orleans for $1,000 with an extra hood, hatch, and a box full of parts.
I never would trust new paint unless you know there is no bondo like they have been saying, but most people do a paint job to cover the rust up
It's missing a Hood louvre, has pretty bad rust on the hatch, has crappy wheels and will most likely need new tires, and it could be non-op because of a rusty fuel tank, electrical problems, etc.
The hatch area looks pretty clean from teh pictures though, mine has rust on the flat portion where the hatch latches, and that one looks pretty clean.
The interior looks good though. Depending on what the car looks like in person and the actual amount of rust, I'd say $1000 at the very most for a non-running 280Z.
