Nintendo has turned to West Coast Customs to build life-sized Mario karts. The real-world Mario Karts were debuted at the 2011 LA Auto Show and were created to promote the release of the newest Mario Kart game. Mario and Luigi's rides served as the inspiration for the project.
Reportedly, the two karts built are fully functional which is a dream come true for millions upon millions of gamers out there. The karts were built for promotional purposes and will be given away to gamers after the game's release. To have a shot at winning one of the two life-sized Mario karts, all you need to do is become/be a member of GameStop's PowerUp rewards program and buy a game or trade one in during the month of December.
