Larry the Cable Guy voices Mater in Pixar's Cars.
Mater is a rusty tow truck who lives in Radiator Springs and becomes Lightning McQueen's closest friend. His name is a shortened form of “tomater,” reflecting the character's Southern rural speech and comic personality. Mater is enthusiastic, loyal, and often unconcerned with how others judge his worn appearance.
Larry the Cable Guy, the stage name of comedian Daniel Lawrence Whitney, provided Mater's voice in the Cars films and related productions. The character's accent, tall tales, and friendship with McQueen became central to the franchise's humor.
Mater is sometimes mistaken for Guido because both are associated with vehicle service and racing. Guido is a small Italian forklift voiced by Guido Quaroni. Ramone is the town's lowrider and paint-shop owner, while Fillmore is Radiator Springs' Volkswagen-style hippie van.
