It could be Joe Blow's 917K and it would still bring high seven figures, maybe eight.
There was one of these owned by a Cleveland area dealer family at the vintage event at Mid-Ohio years ago.
They probably bought it when it was just another obsolete race car, and these were made in what would have to be considered large volume for what it was, since both Porsche and Ferrari had to build at least twenty five examples of these accident out of the FIA rulebook five liter cars to homologate them. Yeah, I know that the 917 was actually 4.9 liters.
