Herbie's name is mentioned only once in the film. This occurs when Pete first picks up Herbie at the beginning. The owner of the car lot tells Pete a story about Jim Douglas and says, "Herbie, he see it, he stop." For the rest of the movie, the car is called Ocho.
Herbie The Love Bug was a 1963 Volkswagen Beetle deluxe ragtop sedan painted in Volkswagen L87 pearl white. Under normal circumstances, the interior would be a matching white. However, Herbie's interior was painted a special non-reflective grey color so the camera and studio lights would not reflect.
