Here's general view of almost all of my Knight Rider stuff:

Note the cardboard KITT, cutted it in the 80's from some cornflakes box, don't remember anymore what the exact brand was or any other details.
Also my "KR, the Best Of" and the 1st season DVD boxes have Finnish coverart and are the region2 Scandinavian version with Finnish, Swedish, etc. subtitles. The season2 DVD box have the original English coverart but includes the Scandinavian countries subtitles.
The small KITT is just a Majorette Trans-Am with red sticker as a scanner added by me
