This show picked young car owners living in Los Angeles or elsewhere in Southern California and customises their vehicles at no cost to them. An episode of Pimp My Ride generally begins with the participant showing his or her car off, and convincing MTV why it needs to be "pimped". After this segment, the host (normally rapper Xzibit, but occasionally guest hosts such as Chamillionaire) shows up at the participant's house, takes a look at the car himself, makes wisecracks about the particular things that are wrong with it, and promises the owner a complete makeover of the vehicle.
