Couple months ago I sold a running driving 71 Duster slant 3 on the floor. I had repaired all the rust, smoothed out all the dings, did the brakes, gas tank, priced at $3500 here in SE Tx GM land. The second guy bought it, no haggle, as it was the best car for the best price available. Advertised 2 months and 2 lookers! But I can look on CL, FB Marketplace, and see 6-8 Dusters, all total POS needing everything, all pried higher than they will ever bring. I know, you can always come down. But if I am hunting a car, I rarely ever call on stupid priced crap.
I could have lots of guys see my ad back East and say " nice car for the $, wish you were closer, wish I had the space, wish my wife would let me!"
Whats hot and whats not follows trends, the flavor of the month, thus interest in Smokey Bandit TA's and the rest. Part of what take away from the collector car market is NEW muscle cars, and my generation just getting older and woreout!
