It's really about the quality of the steel. Alfa Romeo made some cards in the early
80's that rusted so fast it was amazing. I think Dodge has some similar problems in
the early 70's. Remember the Duster? They turned to dust! I used to think it was
paint problems. That may be some of it but good steel will rust much more slowly
than lousy poor quality steel.
