Tons of KR pics online... but which ones do you have that you haven't seen?
Here are a few...

This was from some teen magazine in the 80's (uh, I was a teen!) and check out the Kitt car... It looks smaller than the actual Kenner car... seems to have something under the front nose / wheels.... no t top bars and a dull finish... and tinted windows (which Kenner did not have)....

David "talking" with Danny Sullivan, a famous race car diver in the 80's....
I think this was more a publicity shot, because as they said, David learned quick and did much of his own driving after 6 months or so...

The puffy stickers... I had another different set, a helicopter chasing Kitt, etc... the Poster (in card form) that I had as a kid (Michael kneeling by Kitt).... A cut out of the Kenner Kitt car, notice, same stuff under the front wheels... and the nose looks much better than the toy I got... it looks to be the same as the one David is holding in the first pic, but different than the final retail model...
And one of the TV Guide spots for KR... I have a bunch, probably not all, but a lot of these...
Alright... show me whutchu got ?!?!?!?
