Continuity mistake: When Herbie launches the bananas on the propeller of the villains' plane, the blades cut up the bananas, covering the villains. At this point, Quinn (the villain in the black suit) has his glasses in his mouth and he takes the glasses with his left hand whilst wiping the banana mess off his face. In the next shot, his glasses are now in his right hand.
Trivia: When Herbie is made to "walk the plank" on the cruise liner, a real Volkswagen Beetle was thrown into the sea and was never retrieved.
D.J.: Why do keep calling this car Ocho? Ocho means eight. Can't you read the numbers?
Paco: Sure I can read the numbers. Five and three are eight. Anyone knows that.
