Trophy Information
This rally car tore up dirt and raced through uncharted lands in the Disk System game 3D Hot Rally. While it wasn't as fast as the other two car types, it had super-strong shocks to deal with horrible roads and other obstacles. Mario and Luigi are in command of this car, although they don't show themselves in the game very often.
