Revealing mistake: There is a scene where KITT drives over to Michael, and you can see the drivers seat is really a guy dressed up in a light brown suit to look like a car seat.

A Nice, Indecent Little Town - S1-E17

Revealing mistake: As KITT is rolling down the hill with the unconscious Michael inside, the shots of KITT from the outside show that the bonnet and roof have large and obvious gaps between them and the rest of the bodywork (presumably a stunt vehicle).

Good Day at White Rock - S1-E4
