1970 Porsche 917/10 Prototype

With a substantial racing history of its own, this 1970 Porsche 917/10 Prototype was also instrumental in helping Porsche's racing team. Early on, it was used as a test mule of sorts, logging plenty of test miles both in the wind-tunnel and on the track. During the same period, it was fitted with several different engines, as well as five different body designs. The chassis was completely rebuilt in 1972 before being sold to the first of only four private owners. In the years since, it's been raced around the world, fully restored not once, but twice — in 1997 and 2014 — and is now presented in the same livery it wore during wind tunnel testing in 1971. It arrives with its yellow Bosch livery Shovel-nose and matching rear bonnet, tons of historical material, its ONS Wagenpass, a report from former factory racing driver Jürgen Barth, and a current FIA Historic Technical Passport. As the first 917 Can Am Spyder, the only "001" 917 chassis in private ownership, and with a pedigree that's second to none, this is one of the most unique racers of its time.
