Both CRX's and $750, or no deal. I'm not even voting on this one, and I tried *so* hard to ignore it, but I can't anymore.
If you trade for either of those cars, and you don't get a buttload of cash for them, I'll drive to SC just to slap you silly.
(Metaphorically speaking, of course - I'm not a violent person.)
But seriously. Both and $500, minimum, for your trouble. Neither of those CRX's is worth more than $500, regardless of "engine's been rebuilt" because he can't prove it, even if it does have receipts, unless it was done by a shop. Given the condition of either car, and the known reliability of Honda engines, neither of them would have needed to be rebuilt if doitch there didn't own them anyway.
The only real plus to either one is the (apparent) lack of rust. That'll make it a nice chassis to work with.
