Have you ever looked on the Manheim auction for 4th gens? I have. They all seem to be from Ohio, Mich, NY, Penn, Mass, etc. I know there are used car dealers in Denver who bring these here to sell at our higher than average prices. Even buying in CO doesn't guarantee a rust free car. Mine was a one owner from Craig traded in at Rifle. When I first saw it it was a mess but I was pretty sure it was all just dirt. Dealer's detail team did a great job and it came clean. There were rust stains on the paint the size of a silver dollar that were from a paint chip no bigger than the head of a pin but neglected for who knows how long. A little polish and touch up and like new. I'm still wondering how a dirty 100k mile interior can clean up to showroom condition. The materials in these cars are great.
