Stop and think about that for a minute. Would you really go buy the originals? I'd still own kit builds, it's just that they'd have everything I could ever dream of in them. And I'd hire a mechanic to help build and maintain it all full time.
Or maybe your own personal autox team...
Nascar? Buy your way in?
F1?
ok maybe not.
Besides there's much better hobbies for speed. With that kind of money you could buy a REALLY nice airplane and fly it for the rest of your life.
Run your own reno air racing team?
Or what about your own X-mission team? Ever wanted to go into orbit?
The possibilities are mind numbing.
