Though a 1969 Dart was built by Barris to replicate this car in the show's 1969 season, the 1968 Dart was regularly seen during the 1969 season. (In the 1969 episode "A Penny for the Peep Show", both the 1968 and 1969 Darts are used in the same shot, to elude a police tail on Mannix, but no explanation in the episode was given for why or how two identically customized green Dart convertibles show up together.)
