The 18-22 Series film assessed
Once the film had been shown to dealer principles it was then stored away for posterity, all but forgotten until Motorfilms released it on a British Leyland compilation DVD in 2005. An edited version with new car footage was created to coincide with the Princess launch in September 1975. When the O-series engine was launched in 1978 a new film 'Test Track' was created showing the cars under vigorous testing at the Nardo test track facility in Italy. The TV advert can be seen here. An extended version of the advert was shown in cinemas and a longer 20 minute version was also available for dealer principles.
