What to pay for this 71 Dodge Demon

I haven't seen it in person, that's why I was trying to get some pics from him. Motor has been bored, new cam, new pistons of course, carb aluminum intake. I was afraid of the paint too. I'm not sure why they did that tail section like that?? I was feeling him out and he said somebody offered him 9500 for it but hadn't seen him since. He said he would take 9 grand cash for it now though. I thought it would be closer to 5 or 6. But like you said you never know what's under there?? These things seem to be all over the board on price though.
