Revealing mistake: As KITT goes up on two wheels to go between two cars in the Demolition Derby, it's the stunt driver.
Nobody Does It Better - S1-E21

Continuity mistake: When Julian leaves the building during the party, you can see this isn't the actor playing the role of Julian but someone else. (00:23:10)
Nobody Does It Better - S1-E21
Continuity mistake: When KITT forces the 4x4 off the road, you can see both people inside when it crashes wearing their safety harness. In the scene before when you see inside none of them are wearing any kind of belt. (00:37:40 - 00:38:15)
White Bird - S1-E19

White Bird - S1-E19
Continuity mistake: When Michael and Stevie are in the car and it jumps through the panel on the trailer, when the car lands and it cuts back to Michael there is no trailer in the background. (00:17:05)
White Bird - S1-E19
Continuity mistake: When Michael is racing to the airfield to stop the bad guys, when you see inside the car it is clear and sunny outside. Next shot of outside with the car skidding the driver is wearing a different costume, possibly taken from another episode. Then the outside is foggy, back to clear, then foggy as he approaches the jump. (00:39:15)
Continuity mistake: When Michael is in K.I.T.T and he is taking the professor's blood pressure, the boot is open. When it goes to an outside shot of K.I.T.T driving away it is closed. (00:03:50)
Continuity mistake: When Michael rescues Bonnie and asks K.I.T.T to meet him, one minute it is night time, next scene bright daylight. If it was morning it wouldn't be that bright. This is where they have possibly used footage from a previous episode. (00:26:20)
Continuity mistake: When they arrive at the museum and start to unload K.I.T.T it is raining fairly hard. When it cuts to Bonnie and the Professor and the woman it isn't raining. This keeps happening throughout the scene. (00:38:15)
Continuity mistake: When the guy in the phone box is shot, and Michael yells for K.I.T.T, once K.I.T.T stops the front wheels are facing to the left. But when Michael drives off they are facing right. (00:13:15)
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.
