The 1987 Chevrolet Caprice Estate was a station wagon used by Mike Ehrmantraut.
Better Call Saul
Mike uses the station wagon as one of his spare vehicles. He follows Nacho Varga's van to a hideout in the desert as part of his plan to assassinate Hector Salamanca. However, Mike is distracted when he hears a car horn blaring in the distance. He traces the noise to the station wagon, where he sees a branch propped up inside against the horn and a note reading "DON'T" left on the windshield.("")
Mike realizes he is being watched and flees the scene. He drives the vehicle to a junkyard, where he spends hours methodically taking it apart in search of a tracking device. Mike eventually has an epiphany and takes the fuel cap apart, where he discovers the tracker inside. He abandons the wagon at the junkyard and takes a taxi home.("")
