One of the stars at the recent Techno Classica was this Porsche 911 ST 2.5 that was restored over a 2 1/2 year period by Porsche Classic themselves. One of around two dozen built in 1971 and 1972, this car was acquired new by American Michael Keyser, who raced it in the World Championship together with Porsche's Jurgen Barth. It also served as a camera car for Keyser's fantastic documentary 'Speed Merchants'. An absolute highlight of the season was a class win at Le Mans. Found in rather derelict condition, the rare and very successful 911 ST 2.5 has been brought back to its Le Mans winning glory.
One of the ST's successors was the 911 Carrera RSR 3.0 and at the Jarama Classic, we were treated to the very example that won its class at Le Mans in 1975. Having spent over three decades in Portugal, it has now finally been resplendent in its Le Mans winning colours.
Another very rare Porsche on display in Essen was this 935 K3, which is the only one finished in road legal specification. Built for F1 team principal Walter Wolf, it features a full upholstery but was still capable of speeds of over 330 km/h on the Autobahn during a pre delivery test. Beautifully preserved, this unique 935 K3 was offered for 2 million Euro.
Equally rare is the Porsche 911 GT1 Evolution consigned to the upcoming RM Auctions Monaco sale. Raced extensively in North America, this was the only Evolution model supplied new to a customer. In more recent years, it was made completely road legal by Lanzante and has a pre-sale estimate of Euro 2.7 - 3 million. Our 29-shot gallery also includes shots of one of the three works cars.
