Father and son builds are very cool projects to take on. Just sit down and make a realistic plan for the car and stick to it. It's easy to go crazy once you get into it but keep to the plan and have a good time. Don't throw anything away even if you don't think you'll use it. You never know. My son and I built a car when he was in high school mostly to keep him out of trouble(for him) and to give us time to spend together before he would go away to college(for me). Probably made it even tougher when he left because we spent so much time together but worth every minute. Of couse it's been 8 years now and I really could use that extra stall in my garage but what are you going to do. He won't even talk about selling it.
