I'm still hyperventilating over that polished aluminum Veyron. Man, I'd love to build that thing!
Here's another one I've wished I could build but no kit exists:

Yes, Lindberg attempted a kit 50 years ago but it's so bad scratch-building one from mud and twigs would be easier (and faster probably...) The car has a supercharged Lycoming engine in it. Even the color of this is kinda cool: Cigarette Cream. Gotta love the 30's!
