Tow Mater

Tow Mater, known by his surname Mater (also known as Sir Tow Mater) is a rusty old tow truck. He is Lightning McQueen's best friend and the owner of the local junkyard in Radiator Springs. Two of Mater's catchphrases are "Dad-gum!" and "Git-R-Done!" (the latter of which is his voice actor, Larry the Cable Guy's signature phrase).
