Which real car model inspires Fillmore in Pixar's Cars?

Fillmore in Pixar's Cars is inspired by the Volkswagen Type 2, commonly associated with the Volkswagen Bus.

Fillmore is Radiator Springs' friendly, peace-loving owner of Fillmore's Taste-In, an organic fuel shop. His rounded body, large front window, and colorful 1960s-style appearance reflect the visual identity of the Volkswagen Type 2 camper van, a vehicle strongly associated with counterculture and road travel.

The character's name references Charles J. Fillmore, a co-founder of the Unity School of Christianity, while his personality draws on the stereotypical peace-and-love image linked with the Volkswagen Bus. Fillmore argues with his neighbor Sarge, a military-style vehicle, over fuel and lifestyle.

The Volkswagen Type 2 began production in 1950 and was developed by Volkswagen as a van based on Beetle mechanical components. In different markets it has been known by names including Transporter, Kombi, Microbus, and Volkswagen Bus, but those labels refer to the same broad vehicle family represented by Fillmore.
