Number one for me would be KITT for sure. I also like one that no one has mentioned. The custom Firebird Steve Martin drove when he became rich in The Jerk. Lol and his long feather hat sticking out the T-Tops
Ever since I was a kid, I've been dreaming of having one, and I mean dreaming - as in praying every night that somehow I would ended up with the model from the TV show on my lap. Silly kid I was.
There are kits out there that sci-fi fans have been putting together, and boy oh boy, am I thinking about getting one and try to replicate what's done here:
I was born in '70 and hands down loved Smokey and the Bandit's T/A. The coolest thing was when my older brother took me to school in his that looked just like it.
