Starting in roughly the second season, a sharp eyed viewer could begin to spot non T-top versions of K.I.T.T. on the screen. The producers were very clever in their attempts to make the cars look like they had t-tops: they applied trip pieces where the t-tops seams would be. Also, non-top cars received a boxy overhead console as opposed to the form fitting one seen in the t-top version. Check out some examples below, including an interior shot of a hardtop car.
