Man builds his own million dollar Bugatti supercar by hand http://news.yahoo.com/blogs/technol...n-dollar-bugatti-supercar-hand-211223675.html
No performance = no sale for me. Granted the car looks beautiful, but to not have the incredible engine that comes with the genuine article kills it. Still, at 89000$, it's not like you could actually expect to get the real bugati engine.
If you had the nous, just take the 2.5ltr V6 out and replace it (if possible) with perhaps the 5.0ltr V8 Coyote? Or you could put a twin turbo on the V6.
