Having seen the interior now, and even with the uncertainty about why it was parked, my estimate of what it is worth is above what he is asking. It likely wouldn't take all that much to get it road ready and clean it up and install an NOS trim strip on the front fender and buff it and sell it to Europe for double that amount, the only "if" being whether Europe would really go for one without a big block. If that were a 72, I would have bought it by now...............................
I do wonder what is going on at the front of the car in the first photo with all the boxes up there and some metal pieces as well. Are they hiding anything?
