Is it possible that all the affordable project cars are now taken?

If the OP will define a budget, I'm sure most of the FABO/FxBO family will take that as a challenge to find suitable cars to at least investigate or asses actual market conditions if not purchase.

Might also help to at least loosely define the target.

Anything 62-79?

...or only a 2 door with manual transmission from 68-72?
