If you really want to establish a value, a Marti report could be suggested. If it was a fully equipped vert, even with a 302, it could be desirable. If this car was in class 2 condition, it could be worth about $30,000. If the price is $9500, if it could be put in class 2 condition for another $20,000, $9500 is a good price. I would guess it would cost a lot more than $20,000 to get it nice if you paid someone, so I think that is a high price. But if someone wants a fully optioned vert, they might pay this price. Otherwise, I would think it is high.
I have my own red 69 convertible, 302, fully loaded.
