11. Ferrari P4/5
James Glickenhaus is clearly the front-runner for the title of "petrolhead of the century" for one reason and one reason alone: He commissioned the amazing Ferrari P4/5. It's a faster, more refined, and infinitely more sexy version of an Enzo and easily one of the coolest vehicles ever made. More still, this isn't just some rich guy's show piece. Glickenhaus races the thing.
