The photos show the bad rust. 99% of the rust is surface.

Even the bottom sill pannels are not too bad. Some rust as would be expected but nothing too bad. Its unrestored etc. 100% original paint. (under the cheap crap paint that is peeling off. This is what has reacted with the paint underneeth making it get some surface type rust.
Doors are rusted out. It appears they have been replaced at some stage.
