You are looking at a windows out re-paint at a minimum. Looks like rust around a lot of the glass, probably water leakage. ...& so probably a bunch of metalwork too. Looks like it sat out in the elements, probably for years. (based on the location of some of this rust) Also looks like it may have had "rust treatment" when it was new, always a *huge* mistake bc it would block the drain holes (rust around the bottoms of the doors, etc) The real "killer" spots are what you can't see here - how is the floor, suspension attachment points, etc. If the outer body is that bad, what kind of shape do you think the engine is in? Get it up on a lift for sure and make sure the structural areas are sound. Rust repair was always the major cost in our shop. It could easily take >100 hours to DA the thing down, pull all the glass, repair the metal, and build it back up and paint it. You could easily be looking at a full suspension, full brakes, at least partial interior, fuel lines, possibly an engine re-build... Anything is fixable for enough $$ but is the juice worth the squeeze? (do you own a Mig welder and a plasma cutter? Have you always wanted to?
