The Mustang II Ghia (with the sport appearance package) normally driven by Kelly is not seen. It has been replaced by a standard Mustang II Ghia. Kelly's car has the lacy spoke rims and this one has the standard hubcaps. Also this Ghia does not have the black stripe going across the back of the front seats.
Rene Auberjonois (Terrence) later appeared as a different character in season four's Angels on Skates (1979).
In the background of a scene with Jaclyn Smith is a small framed photo of child actress Pamelyn Ferdin.
