Why not just take a weekend to fly to where used cars are unrusted, and drive one back?
Also, there are quite a few well made older cars that are fully galvanized and don’t rust. I know a few people in the Northeast still driving 1980s Volvo 740s, still unrusted after nearly 40 years of salty roads. 1987 and later had the best rustproofing. I believe many older Audis also are galvanized.
