OK, I 've never built one, but people build replica/component cars all the time (not VW kit cars with title) so it can't be brain surgery. Although I'm sure some states might be more involved than others.
There was discussion on another thread about this and basically if you have all the paperwork/receipts from the manufacturer it's doable.
I want one of these badly as well. But rent and eating sometimes have to come first.
Damn it!
