Is this 65 barracuda worth $500

Buy it (offer less than $500), take it home and spend some QUALITY time evaluating what you have. Best case scenario: It will clean up to be better than I looks in the pictures a and be a good restoration candidate. Worst case scenario: You decide it is too far gone to easily restore, so you part it out and pocket at least (I would guess) $1500. Either way, BUY IT!!!
