I don't see the rust as being as bad as others believe
The pictures might make that impression. - In my experience, if the corrosion is so obvious on the outside, its a lot worse on the inside.
Whats clear on the pictures
-The Sills are just finished, take a rubber hammer and a dustpan you wont have to screw anything off
-Underfloor and floor panels are heavy corroded.
-Rear wheel Arches are still covered with paint but thats it.
-Fenders on the front are inrepairable, an exchange is easier.
Whats not clear
- Rear Window Frame ok?
- Doors? If the sills look like this the lower edges of the door mostly look worse. Also lot of welding or exchange.
To fix all these Zones its inevitable to strip the whole car, after that a complete paintshop... and thats just for the chassis. Nothing done on tranny, engine, suspension, axels... and there is a lot to do for sure.
Sure, if its legit you migth get it runnin somehow, but who wants to drive a trashcan in such a pathetic condition? Taking it apart an saving the precious parts is the best thing man can do if a full restoration is no option.
