In the movie "Public Enemy No. 1" (released in 1931) James Cagney and his buddy have just left their new La Salle all weather phaeton (GM for convertible sedan) to the valet at a swanky night club. The valet jumps into the La Salle to park it and grinds the gears real bad. Cagney yells: "Hey, that ain't a Ford!"
