Where are the a bodies going

I've been looking for a nice clean duster, dart, scamp for a while now. There hasn't been a mopar on craigslist in Missouri for a long time now. I don't have the resources and time to travel to check out cars that's why I've been looking in the area where I live. There's not much of anything out there, is the classic car market drying up?
Are you looking at two doors only? four doors are becoming very popular as well.
