How much would you pay for this 77' Corvette?

The kelly's blue book site goes further back years there should be a icon that you can click on on the web page. I don't know that much about corvettes Likely the buyer will be someone who knows about corvettes. Blue book valve are only appraisals so don't get too set on the low, high retail price. If the car is not running you will likely get less. If possible clean her up a little elbow grease goes a long way. Good luck
