The car that Jim Bergerac (John Nettles) drove was a 1947 Triumph Roadster. It was very temperamental and caused immense problems during filming when it refused to start, or to stop if the brakes failed. The engine sounded so rough that the sound of a Jaguar was dubbed over the top. Nettles loathed it because he kept scraping his knuckles or banging his knees on the dashboard. After filming on this show had finished, by which time the car was in very poor condition due to its extensive usage, it was auctioned for £34,000 sterling as part of the Children in Need appeal. The new owner later wrote an angry letter to John Nettles complaining about the state of the car.
