For quite some time, a guy named Doug Stevenson in Ohio owned two 1976 Gran Torinos that were both used in the second through fourth (final) seasons of the TV show.
Doug kept a low profile, but the community of Ford Gran Torino owners learned about his TV show cars when the Fairlane Club of America published a story about them in their magazine, The Fairlaner.
At the time, this car (Doug called it "#1") looked exactly as it did when the TV show ended. After Joe C. bought it, though, he had it completely restored.
This Gran Torino has chrome mirrors, body side mouldings, black horizontal bumper mouldings, silver-colored bumper filler panels, and vinyl bench seats. It has a 460 4 bbl. engine and many more options.
You can see a very interesting "Featurette" about the TV Show Torinos as part of the Bonus Materials included with the "Starsky & Hutch" Complete First Season DVD Collection.
