I have only the faintest of memories of this film.
I couldn't of been more than seven when my mother took me to see "Superbug"... a clear "Herbie" ripoff with some "Bond car" thrown in.
I remember only one scene clearly: that of the car scaling the walls between two buildings in the alley. Rather than "pull a Herbie" and just drive up the wall, Superbugs wheels extended outward between the buildings and then slowly (secretly in the night) climbed the building. I have no memory of what it did once it reached the top, but I just remember thinking how cool it was for a car to climb a building that way.
I don't remember the movie as being a comedy but instead a "secret agent" flick with a car in the "James Bond" role.
I've looked for a copy of the movie ever since, but no luck.
