While prices of classics have risen, there are still decent buys out there. What I find is when a "buyer" says "everything is super high" I just offer them a car and say "Put up or shut up"... LOL. I've offered great running, solid Dusters for like 6k with V8's and 8.75 rear ends and those eager buyers just disappear into the fog... :D
it's because lots of people that have disposable income now, still think that these cars should still be priced like they were in the 1980's when they had disposable income then!
****, the house you're in has probably doubled or tripled in price in the last 25 years, why wouldn't these cars come up too? the premium stuff is high and going to stay high, the middle of the road stuff is higher than it's been, but that also a result of supply, but that might see a slight correction. the bottom end benefits from the the other cars being more pricey, and they think they can ask more-- and will usually get more (circle back to supply).
but this is all besides the point, as shown there are still deals out there. it's just that old mopars aren't stacked up like cordwood any more is all.
