Muscle Man's car (also known as the Muscle Machine) is a black car that appeared in several episodes. Although Muscle Man is the owner, it is also frequently borrowed by Mordecai and Rigby.
The car resembles a 1981-1989 Dodge Diplomat, with styling cues from the 1980-1985 Chevrolet Caprice and the 1983-1991 Ford LTD Crown Victoria. The car is black in appearance, but is shown to have rust on the body. The car frequently appears in bad shape, in one episode the engine block fell out through the bottom of the car. Muscle Man states in Every Meat Burritos that the car has an Automatic shift.
