In most seasons, Malloy and Reed always got a new car at the start of the season, which should have been a 1970 Mercury Montego in season 3, but was the previous year's 1969 Plymouth Belvedere. However, in season 4, they got a new 1971 Plymouth Satellite.
Opening for this season features the 1969 Plymouth Belvedere (note the split grill). However after the first shot of the car peeling away on pursuit, all other scenes of the opening sequence features the 1968 Plymouth Belvedere (note one piece mesh grill) prominently featured in the last wide shot as they arrive at the crime scene. The 1968 and 1969 Belvedere are both used throughout season 3 until season 4 when they change to the 1971 Plymouth Satellite.
