I watch Adam-12 and Emergency! almost every night as they are back to back. Not sure why I pay money to watch re-runs (could have something to do with "current programing"... but anyway on some of the Emergency! episodes the windshield wiper arms on the Dodge truck are black while some episodes are the correct stainless.

The car used for Reed and Malloy's close-ups was towed by camera car. The car's windshield showed reflections of the camera and crew, so the car's windshield was removed. However, this led to the wind blowing Reed and Malloy's hair, so a shield was created to enclose the camera and front of the car.

The missing-windshield thing is really noticeable on some shows. The Beverly Hillbillies did it, too, with every car in every scene shot on a soundstage. Windshield out, windows down.

Adam-12 reused a lot of B-roll, and I think that may have been a factor in their continuing to use the '69 Belvedere for an extra year instead of a '70--they had a ton of footage with the '68, shot during season 1, and they reused that with the '69. You can see the '68 marker lights in a lot of the drive-by footage.

I have noticed that sometimes when the view is looking out the windshield from inside their squad 51 it appears it's NOT a bird bath hood.

Maybe this truck? It was on the show, but from a different squad. I vaguely remember John and Roy driving a similar truck......

Besides seeing what might be film crew member's cars parked or driving by multiple times in episodes of both Emergency (light blue VW Bug) and Adam 12 like this Mercedes SL there is also something that a few city car drivers used for parallel parking. Can you spot it in the third image?

One major goof on Adam-12 happened in the episode at the Police Academy driving school. Malloy drives around the track in a '68-'69 Belvedere but the inside shots show a Matador dashboard and interior.

The Blues Brothers 'cop tires and 440 plant' speech looks like it was based on dialogue spoken by Malloy in episode one of Adam 12.

I agree that they had a little motor pool of vehicles that showed up in many episodes of Adam12, Dragnet, and Emergency! I'm into flathead six Plymouths and they had a green '49 Club Coupe that popped up in several episodes.... with the Plymouth name taped-over, of course.

My son and I spotted it also this past Sunday during the second episode when the motorcycle officer Grant went missing. The scene was in a parking lot with Sargent McDonald standing outside Malloy's driver's window but Malloy's partner officer Reed was also heard talking even though he was on the other side or the car. That's why we were guessing it was for a microphone as there was no in car camera work for officer Reed. The camera zoomed out and Malloy backed away out of the lot and there was no evidence of a boom microphone and you couldn't see the front of the Matador so a quick disconnect of the mic is what we figured. Couldn't figure out why they didn't run it down the passenger's side of the car? I'm too busy looking at the other passing cars, the cars parked on the streets and the ones in the parking lots to always keep up with the episode plot. BTW Jack Webb had the car's windshield remove after the first episode for those on trailer or film screen behind the car scenes. And the inside rearview mirror is always moved up as much as possible. Yeah too much time on my hands at the moment

That's wild about the windshield! I wonder if the pieces were just plexiglass?
