Lizzie is a 1923 Ford Model T voiced by Katherine Helmond. Her license plate says "MT23" because of her model. She is the widow of Radiator Springs' founder, Stanley, and the elderly owner of a roadside souvenir and accessory shop. When Lightning shows how much he contributed to the town's lighting, she says to the Stanley monument outside of Red's firehouse, "I wish you could have seen this". She has gone a little bit senile because she is so old, and has a crush on Lightning McQueen.

The name "Lizzie" is a reference to "Tin Lizzie", the popular nickname of the Model T.

The Lizzie diecast car is one of the least distributed, so it has some degree of rarity.
