Luigi -- Mini Cooper D

Luigi's the eternal sidekick, doomed to a life of playing second-banana to his Mario. His brother gets the name, the action and the girl in almost every game, while he's lucky if he gets to show up. This doesn't mean he doesn't have his own sense of style, though. While Mario would take the bright red Italian sports car, Luigi would sit behind of the wheel of a Mini Cooper D.
The Mini Cooper D screams "I'm different!" by combining the offbeat style of the original Mini Cooper with the remarkably high fuel economy of a diesel engine. Mario's expensive speedster might get there faster, but he'll have sold it to pay for gas by the time Luigi putters up in his funky, functional ride.
For style, the Cooper really fits Luigi's awkward-but-beloved character. Stylish with just a hint of dorkiness, the sporty little Mini is the perfect vehicle for Mario's underdog brother.
