Continuity mistake: When Squad 51 is dispatched and headed to their destination, interior shots looking out the windshield are shown. It is only in these shots that the Dodge truck's red hood has vents on its right and left sides. There is no such thing in any exterior shots of Squad 51. The hood's style also changes.Super Grover
Continuity mistake: In nearly every episode, the dark blue jackets that Gage and DeSoto wear suddenly appear and/or vanish and then reappear, numerous times, while en route in their squad, or when they pull into the stationhouse and Rampart. Since stock footage is usually used when showing all the guys getting into their vehicles, Johnny's hair length may differ as well.Super Grover
Continuity mistake: Frequently during the first two seasons there will be long shots of Squad 51 running down the road but it has mysteriously become a mid-60's Dodge (easily visible because of the red painted grille) instead of the familiar 1972+ model Dodge with a chrome grille. It also has 51 on the door which makes for a significant paradox.
