I watch a 1964 sell today in Birmingham at auction for 17k plus 10% buyers fee.
It was a decent driver with tired paint, little bondo, fair interior, and no rust that I could notice with a pretty good get on my back under the car inspection. The trunk floor looked newer. Other floors were original and solid.
The car seemed to run ok, but you really onlyr hear it run when cold and for a few minutes.
The top and interior were about a 7. The tires looked good.
I bid it to 13k. I put it at a 4 plus/3 minus car.
