Trivia: A Car's Life: Sparky's Big Adventure
- Cross-Dressing Voices: The voice of Sparky and Norbert is Corinne Orr, a female who was born in 1936. She also voices Walt the Pig. And what a coincidence that they are almost the same! The only difference is that Sparky's a car and Walt's a pampered piglet.
- Hey, It's That Voice! / WTH, Casting Agency?:
- The Other Darrin: Sean Schemmel and Jim Woods take over Glen Gomez's roles as Fender and Clutch in the sequel due to a diagnosis of Alzheimer's disease forcing Gomez into retirement. Norbert and Gracie also have different voice actors in the sequel, though they are uncredited.
- Real-Life Relative: Sparky's little sister Gracie is voiced by Michael Schelp's real-life daughter (niece?) Grace, and the Gas Leech's son is voiced by his real-life son (nephew?) Mark.
