Are we talking about the same car? I'm looking at the pics. I see major rust through in the lower qtrs, rust through in the sail panels, and major rust through, around the rear window.
I repair this stuff for a living. Just giving you my professional opinion.
If it's your car, post a correct "FOR SALE" add. Just posting an ebay link leaves it open to be criticized.
The car is clearly misrepresented in reference to the rust.
