What car does Jake Peralta buy on his first day as a cop?

Jake Peralta buys a 1967 Ford Mustang on his first day as a cop.

The Mustang is one of Jake's most recognizable possessions and reflects his combination of enthusiasm, impulsiveness, and love of classic pop-culture cool. The car is described as a 1967 Ford Mustang, a first-generation Mustang model from the era when the car had become an American performance icon.

Jake's attachment to the vehicle is stronger than a simple preference for an old car. He treats it as a symbol of his identity and repeatedly refers to it with pride. In “The Bet,” he wagers the Mustang against Amy Santiago while competing to see who can make more arrests. That bet demonstrates both his confidence and his willingness to risk something personally valuable for a game.

Viewers may encounter continuity confusion because different Mustang bodies and model years appear on screen in different episodes. The show's established character biography nevertheless identifies Jake's car as a 1967 Ford Mustang. He later sells it to help Terry with expenses connected to Terry's family, making the car part of Jake's gradual emotional maturation.
