NBC aired the longest commercial trailer yet. We show how KITT finds Sarah, KITT meeting Mike, and plot details that might be a bit spoilerish. There is pretty amazing shots of KITT being hit in the windshield and "repairing" himself, and of course lots of action. If you want to keep clear of spoilers - you might want to stop watching thse.
Also another clip that had been airing recently is a Ford commercial talking about how in conjunction with Knight Rider they will be giving away four cars, one being a Mustang. That video is after the jump.
