Mater is a rusty old tow truck and Lightning McQueen's best friend.
Mater's a good ol' boy with a big heart and the only tow truck in Radiator Springs. He runs Tow Mater Towing & Salvage and manages the local impound lot. Though a little rusty, he has the quickest towrope in Carburetor County and is always the first to lend a helping hand. Mater sees the bright side of any situation. He's the heart and soul of Radiator Springs, and he doesn't have a mean bolt in his chassis.
