The rumor that K.I.T.T. will be played by a Mustang in the upcoming Knight Rider TV series appears to be true. That is, assuming someone with a lot of time on his hands didn't mock up a Hoff-ified Mustang just for the hell of it. That's extremely doubtful, as the car you see above is actually wearing the body kit of a Shelby GT500KR, which isn't easy to come by for weekend projects. Nope, if we take the pic at face value, then the only conclusion possible is that K.I.T.T. will be played by a 550-horsepower Shelby GT500KR in black with silver racing stripes.
