I pinched this from Sports Car Digest : "Did not sell at high bid of $6,000,000 versus pre-sale estimate of $8,000,000 - $10,000,000. Ex-works, Hans Stuck and Rudolf Hasse; finished fifth in the 1939 German EifelRennen event on the North Circuit of the Nürburgring and sixth in the Grand Prix de l'Automobile Club de France around the superfast public road course at Reims-Gueux."
Only good ol' Dr Porsche would design a rear-engined V12 racer, and then make it work.
