FWIW, the "ferrari" in the movie was a kit car on a mustang platform.
They were so poorly put together, that they had to have two of them, so that they could have one in running condition when needed...now THERE is a piece of useless trivia.
Loved all the crazy customs created for TV shows back in the day...
Especially when Jethro decided to hot-rod the Clampett family truck.
Hows bout a shout out for "my mother the car"...
