Due to the popularity of the information on The Saint's Volvo, I have created another page all about The Saint's Jaguar. If anyone has more pictures or information they would like to contribute to this work in progress, please e-mail 'saint' at this domain (saint.org).
The Jaguar Model Club also has a great list of all the appearances of a Jaguar in movies and TV and has the following additional information about the Jaguar XJS' role in the Return of The Saint TV series starring Ian Ogilvy:This early prototype 1975 four-speed manual, V12 XJS was driven by Ian Ogilvy in 20 out of the 24 episodes filmed. Replaced by a second White XJS for the last four episodes after Ogilvy, burned the clutch out doing one of those famous get away starts on gravel! The original car was registered PWK 530R but had false 'ST 1' plates fitted. The car survives today and is one of the 352 rare manual versions of the Jaguar XJS.
