To buy or not to buy?

Maybe Barracudas are worth a lot more. If a Dart or Valiant, $700 in CA for one without any patches or significant rust. Might cost $500 to move one to OR, so that might be an upper bound, though buying something far away can add cost. What parts you currently have is irrelevant to the value of this car. I do agree that you would spend much more than you expect to collect missing parts, depending on what you want. Ex. if you are happy with used seats from a modern car, you might save $800.
