Its not just craigslist

A big part of the new wave of interest for these cars are people who are just interested in owning a classic car.
They dont care what engine is in it, or how many doors it has. They care that it is clean, serviceable and vintage.
Perception drives price. If ten people list 67 Valiants for $20,000, the one guy who prices his at $18,500 looks to be presenting a bargain. Suddenly that becomes the new price floor.
Like I said, mark my words...it's coming

I've been saying the same for years. A bodies won't ever be what a Hemi Cuda is... but who drives a HemiCuda to the mall and around town? I've been saying it for a long time.... old A bodies are about to climb.
