Welcome aboard.
I think the best thing to do is spend a lot of time here using the search function. Read all you can about the original cars, that may help you finalize your plans.

The next thing is to check with your insurance company. I could not find any carrier who would allow anyone under 25 to drive one of these cars.

If the car won't be done before you are 25, then it won't be an issue.

Best wishes and keep us posted.
