In the opening titles for the Terry McCann episodes (Seasons 1-7) a sporty white Ford Escort with a blue stripe down the side is seen in the background. In a close-up shot of Terry looking at the Ford Capri he is about to buy, the Escort's window is up, but in a later shot where Arthur and Terry walk from the back of the Capri to admire it from a distance, the Escort's window is wound down.
