Other mistake: In an overhead shot of KITT speeding through the desert after Lauren's plane, you can see parts of KITT's hood wobbling against the wind. I seriously doubt a car made to be indestructible would have that happen.

Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (1) - S1-E1
Continuity mistake: If you look closely at KITT throughout the pilot, the position of his scanner lens changes from being the normal scanner that we're all used to, and the scanner being at the very tip of the front bumper. (The latter case is because the car was used for a promo shots to sell to NBC, and after the show was picked up, they changed KITT's look, but still used the earlier shots).
Michael Knight: I need ya buddy.
KITT: Right away Michael.
Trivia: Even though William Daniels provided the voice of "K.I.T.T.", he was uncredited throughout the whole series.

Answer: I would say that unless there's visual evidence it was another K.I.T.T. car, as in you could see the bar scanner or cut steering wheel, people on here would correct the mistake by saying more than one 1982 Pontiac Firebird Trans-Am was sold and there's no reason it's meant to be a random car.
