I saw this one for sale, fair price, if, now the IF. The rust is not too bad.
Check Sills, especially the front (see your pictures). bottom of windscreen off side, bottom of rear window frame. Spare wheel well (see your pictures) bottoms of doors.
It is all fixable, panels are not too expensive.
Headlights are prone to rusting on the inside, RHD ones are hard to find, but LHD can be used if your change the lenses over, very carefully.
Engines are simple, no major hassles on an aircooled,
Sorry, I am not trying to seem negative. Great cars, fun to drive. Very easy to fix when things go wrong.
