Near the end, right when they show K.A.R.R. going off the cliff, it's actually a clip from "The Car", http://www.imdb.com/title/tt0075809/ where they trick it into going over the cliff then blow the cliff face. If you look closely, you can see the front of the fiberglass effect kit Barris Kustoms put on a Lincoln to make it look unique.The later clip of a car falling into the surf you only see the bottom, but it's not footage from "The Car".It might have been substituted to save money shooting, but i bet it was an inside joke, especially because of the similarity between the title "The Car" and K.A.R.R.I agree with an earlier poster, sometimes the only reason i watch old episodes is to see all the older cars and places in the background.
