How about Killer KITT and the altercation with the traffic warden? "It's not over yet lady!" and KITT opens his door and floors the woman. Now that was funny!

Anyone remember the remote controlled KITT? There were probably several but when I was young, one of my mates had an exact cr replica which had a proper remote control for it (from what I can remember). Also used to have some sort of Matchbox car stunt set which has two Trans AM cars in with a logo ...

Well mine are Killer KITT, Trust Doesn't Rust and KITT v KARR (yes the obvious ones but still the best)
