Wow. Maybe a severe case of acne?
I'd think that almost has to be volcano damage. Maybe sprayed with falling magma spray and then the salt air got to the bare steel(?)
Est value-$4000. $400 for the car and $3,600 shipping to the San Pedro (Los Angeles) harbor port. Yeah, that's it!
In Hawaii, the rust was caused by salt spray. The paint being damaged that allowed the rust to start could have been from volcanic ash (as somebody else posted) or hail (do they even get hail in Hawaii?).
