The Mean Machine, with Dick Dastardly and Muttley.
The Mean Machine is Dick Dastardly's car in Wacky Races. It is the #00 car and it sports many dangerous contraptions that help Dick cheat when he is competing with the other racers.
The Mean Machine is a purple, rocket-powered car/truck hybrid with an abundance of concealed weapons and the ability to fly. Dastardly's rocket car was arguably the fastest car in the series, as evinced by Dastardly's repeatedly zooming to a stunning lead from far behind.
