Only in arid climates. That coupe IS my first car, a '56 A. After 20 years as a daily driver in the east, it was held together by the paint. More rust than metal, really.
Attached is what it looke dlike on its best day in my stewardship, taken at an angle that does not show the rust, nor the dents.
Also saw the video of the million-mile 356 (a C). Also in sunny, DRY SoCal.
