Not 30's but here's what happened to my 88 Cutlass Supreme Classic I had to sell last year. Rust free, 44,000 miles, White/blue/blue all stock V8 4V 4 speed auto, beautifull interior with almost all options, previously owned by a buds older mom who passed away. I had replaced all wear items on the car and drove it daily for a while. I posted for sale on the boards here with no offers. Sold it to a guy across the way and had to watch them transform it with a lift kit etc. Then it got painted (The original looked better than the repaint), including the vinyl top! Add some chrome mirrors, big stereo and dark tints and you're Ghetto Fabulous!!! Now its for sale because he owes money for the stuff and can't pay if anyone wants to save it. Probably still less than 45,000 miles.
