I would say $1000 is pretty high. I have bought way nicer cars for lots less. The yellow car looks to have no fenders on it. The 1/4's on the brown car look to be gone. I am assuming they are both /6 cars. That would say that they have the small rear and more than likely drum breaks. You say there would be no good drivers floor pan. I would say $600 for the pair tops. Looks like you have a few parts cars is all. Sorry.
