Why is it so hard to find a good used Suburban 2500

I sold our 3/4 ton Suburban to a party on the east coast, they prefer vehicles that spend all there years out west because there is no 'RUST' to speak of and they don't even question having it shipped. Check online under 'newsgroups' or 'forums' and be ready to jump on it if it is the one you are looking for. Good luck.
