One other thing you need to take into consideration is yours and your son's skill level. Some kits are easier to finish than others. You need to figure out realistically what you can and can not do on your build. Some folks feel better doing engines and suspension work and others would rather do the body work and not mess with the rest of it. Remember every time you drive your car you are relying on your skill to get you from point A to point B SAFELY.
Above all read all you can and talk to as many people that you can. Call kit suppliers as well as builders and real customers of the cars you are thinking about doing. Get as much info as you can as it is YOUR money you are spending so you need to be sure of what you are getting as well as happy with the final result.
There is a reason they call them kit cars. Just do not fall for the "You can have your car on the road in less than 2 weeks" line of bull. Most kits will take you 100 hours just for the body work. If you can not do that kind of work add at least $4,000 to the cost of the car for the body and paint work.
Above all have fun and do not be afraid to ask for help. To many cars never get finished by the first owner due to a lack of ability or a bad time with the kit and the supplier.
