From :the NYTimes:
“This ethnic and cultural profiling is pretty much par for the animated film course, hence Jenifer Lewis, as a two-tone 1950’s ride with big fins called Flo, provides the only identifiable “black” voice. Less wince-inducing are Luigi (Tony Shalhoub), a banana-yellow Italian-accented Fiat that runs the local tire store; Sarge (Paul Dooley), a World War II jeep as memorable and colorful as dung; and Fillmore (George Carlin), a VW bus who extols the virtues of organic fuel, mutters about conspiracies and raises the Stars and Stripes to the guitar squeals of Jimi Hendrix.”
Nice comment about the jeep character. DANG.
