In 1972, the Porsche 911 ST 2.5 with chassis number 911 230 0538, competed in the World Sportscar Championship, and was the class winner at the 24 Hours of Le Mans. Drivers Jürgen Barth and Michael Keyser raced the car at the Daytona 6 Hours, Sebring 12 Hours and Watkins Glen 6 Hours in the U.S. and in Europe at the Targa Florio, the Nürburgring 1000 Kms and the 24 Hours of Le Mans. At many of the races, the 911 ST doubled as a camera car, shooting footage for the classic film The Speed Merchants. After an intensive search in the U.S., the Porsche 911 ST 2.5 from 1972 was found in California in 2013 and totally restored in exacting detail. A photo taken of the car four years ago no longer matches what it now looks like. Back then, the condition of this historic 911 was correctly described as “ready for the scrap heap.” Over a period of two and a half years, Porsche Classic along with many experts restored it to better than original condition. Its complete race history and the long process of restoration are detailed in the book.
