1969 marked the first win for the Porsche 917 at the World Sportscar Championship. Jo Siffert was the driver that helped Porsche achieve this feat. Hence, to commemorate his victory, Porsche has made a one-off 911. This one-off GT3 RS honors the victory at a 1,000-km race conducted at Österreichring. It was achieved by Siffert and Kurt Ahrens on 10th August 1969. This latest 992-generation Porsche 911 GT3 RS flaunts a unique two-tone paint job. The Pure White with Viper Green accents color scheme is redolent of Siffert's 917. Both of these colors are part of the custom “Paint to Sample” program. The car is adorned with a “29” racing decal. It is the same number used in the inaugural 1,000-km race. The unique satin black magnesium wheels feature the silhouette of the Porsche 917. On the inside, the one-of-one GT3 RS is finished in Black and Guards Red. A unique interior element is a helmet motif embroidered onto the headrests. The one-off car also gets a unique key fob. It shares the same white and green color scheme. A 917 silhouette and Siffert's signature are also embossed onto the key's cover. Porsche's tribute to the fastest man of their 1969 team is a beautiful creation. We are yet to know (or we might not) who will acquire this one-off machine. Source: Porsche, CarScoops
