I have a 1972 Plymouth Scamp that's been sitting for 25+ years, how much is it worth?

RRR, you are such a crank! and this new guy might not get that you are just prodding him for the pics in your usual warm fuzzy way...
I'm not prodding anything. I'm dead serious. If he doesn't understand the need for good pictures to get a good price, then there's nothing I can do. I'm not gonna sugar coat it. If he posted that anywhere for sale with that one picture, the lowballs he would get would be lower than a 100 year old man's cod sack.
