Robot and Henry gave some good advice, and both of them have the experience to speak with a good deal of knowledge on the subject. A few years back I helped a guy with his Speedway Deuce, it was a nice driveable car but certainly not top of the line on quality. It took a lot of hours to get the body smooth and the doors to fit correctly. Whether or not you can turn a profit on it depends on how much value you put on your time finishing it.....It always takes more time and more money than you think to get it done....
