Nobody Does It Better - S1-E21

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)
Continuity mistake: When the bad guy hits K.I.T.T with a log and he says "I beg your pardon", you can see a normal steering wheel inside K.I.T.T. (00:43:35)

Other mistake: When Michael and Marty are being chased and shot at, K.I.T.T jumps over the top of a hill. In the next shot of K.I.T.T driving away, you see a wheel trim rolling down the hill which has fallen off K.I.T.T. (00:39:45)

Revealing mistake: When K.I.T.T turbo boosts near the end when chasing the 4x4 you can see the camera strapped to the side of the car. (00:42:35)
Visible crew/equipment: When Michael is on the beach after finding the body, the camera is on K.I.T.T. In the rear wheel, you can see the reflection off all the crew standing. This can also be seen in the next scene in the front wheel along with the reflection of the lights. (00:03:40)
Continuity mistake: When Michael drives by in K.l.T.T, if you look closely you will see that K.I.T.T has a normal steering wheel and a fake dash with no monitors. (00:32:20)
Inside Out - S1-E10
Continuity mistake: When you see K.I.T.T parked up talking to Devon there is a normal steering wheel on the dash. (00:29:00)
Continuity mistake: Just after Michael wakes up from being knocked out trying to stop the plane, he goes from the front of the Knight semi trailer (where all the computer equipment/office is) they are travelling in to get into KITT. He gets into the driver's side of the car (far side from the camera, indicating that KITT is facing towards the rear door of the trailer. However, in the exterior shot of KITT leaving the trailer, he emerges backwards down the ramp then does a 180 spin to go back the way he was facing when inside.
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.
