This one is a good deal component wise and price too, change the interior out, dress it up, go through the engine etc. You would be all in at well under $20k and if special attention is given to detail, you could sell it for a $10k profit..........
Here's classic one in Nashville, TH for $12,999 on running 1970 chassis.
