The Love Bug (1969 Robert Stevenson)

Yes, the Jane Eyre / Hitchcock Presents director. Written by Bill Walsh and Don DaGradi from a story by Gordon Buford. Dean Jones, Michele Lee, David Tomlinson, Buddy Hackett and Benson Fong (many films since forties). Hippy jokes and crazy scenes with the little car make me think they were stoned then even over at Disney.
