what's this a body worth

Well by looking at one pic, 2500 is the max tops would not go any higher. I would offer 1500 and play the game from there, if as you said the interior is good frame rails good, but needed quarters, then it starts getting expensive. This would make a good flip, buy a 318 on the cheap, piece it together, clean it up, and drive it awhile, if you like the ride, fix it up. If not, you may be able to double your money, it runs and have title in hand, I would ask between 4500 to 5000 for it all day long.......easy.
