As someone that loves old cars that sounds terrible.
Are you sure every car? Some of the higher end European cars have a hot dipped galvanized frame. Volvo advertised pretty heavily that the 1980s 740s were galvanized… I’m pretty sure I’ve seen some that ended up out here on the west coast from the midwest and you can’t undo a suspension bolt, but the chassis was fine.
You could always buy a used car out of state and drive it back.
I haven't seen a hot-dipped galvanized frame here myself, but I would certainly be an interested buyer if any are still be made.
The only cars with aluminum frames are luxury/sports cars, and the Honda Insight from like 20 years ago. Some newer cars have aluminum bodies (F-150?) but not aluminum frames which makes no sense to me. Steel car bodies last a _very_ long time these days, compared to the frames.
