If that's a genuine Road Runner, it needs a lot of help. It looks more to me like a botched-together clone. Wrong grille, terribly-done stripe, totally-failed hood, marker lights filled in to hide the one '71 fender he undoubtedly used, etc. What I can see of the interior is frightening. No open-hood or undercar shots, either. Hard to hazard a guess on value, but were I shopping for something like this I would not even approach a 5-digit offer on the thing.
