Also possible to enter any make and model of car, and get a listing of cinema and tv appearances.
I have previously posted 'Brassed Off' and as I recall the car in which the coal mine manager is chauffeured appears twice in the movie. Although the setting is supposedly 1992/3 a 1995 (year of film) model appears!To make it harder, what about XM's in British TV and film only. Abroad is too easy!
