In Pixar's Cars, Luigi operates a tire shop in Radiator Springs.
Luigi is an Italian yellow 1959 Fiat 500 who owns Luigi's Casa della Tires. The shop specializes in tires, and Luigi takes great pride in Italian racing cars, especially Ferrari. His enthusiasm becomes a recurring source of humor and helps establish the diverse personalities of Radiator Springs.
Guido, Luigi's small blue forklift assistant, works at the same business. Together they service cars and support Lightning during the film's race preparations. Luigi's shop is one of the town's recognizable landmarks.
The business is sometimes described generally as a garage because it is part of the town's automotive world, but its specific function is a tire shop. That distinction separates it from Ramone's House of Body Art, Flo's V8 Café, and the Radiator Springs impound area.
