I see decent cars selling in the 4K to 8K range. Nice desireable cars like big block 66-67, small block 68-70 and 340 A and B body cars up to about 12K.
I'm not talking ultra rare or ultra perfect, but mostly correct or tastefully done street cars.
A guy I work with bought a 61? Chevy full size wagon last week. 90% there, running, driving V8, rusted out tailgate. needed paint. Asking price was $6500. Hope he didn't pay that much.
I Bid 2500 (planned on going to 35) on a 75 Scamp with a sweet 440. Nice paint, a little wavy. Car sold for 4K.
Down the street is a 66 barracuda. Powder blue thick paint with stick on scoops. It's at a buy here pay here for 8K. That ain't gonna sell.
If I found a car like either of mine, with the same options, that was running, driving and had good quarters and decent paint, I'd proabably be willing to pay up to 15K.
