http://www.youtube.com/watch?v=SeUMDY01uUAThis guy built a fully-functional 1/3 scale
Ferrari 312PB from scratch. It took him 15 years. He turned every single part out of metal with his own hands. If you could find someone small enough, it's a driver.
His reason for building it? He wanted to hear the Ferrari 12-cylinder sound but couldn't afford a full-scale Ferrari. I too love the Ferrari scream, but I'm OK with YouTube vids of the real things. His creation belongs, someday, in Ferrari's museum.
