Possible, I did not run a carfax, I just ran away!
But I can tell you this was not road snow/salt rust. The panels rusting through top as much as bottom. Seams that are not exposed, all were rusted through... everywhere. No giant holes at the corners of rocker panel, but seams all rusting through. Wish I took a picture, went with my boss at the time (he was looking for a customer). We were both shocked. I can only imagine it was rusting from inside... Maybe flood damage? idk.
I'm curious if you parked a car on say an offshore oil platform, how it would hold up. Keep in mind that old mustang probably used different steel, and it had 33 years to get there..
