Interesting 916 trivia:
A friend of a friend who is German knows a lot about the 916, his dad had connections at Porsche and a friend who got one of the 11 made (only 1 made it to the US.) He told him most of them went to the Porsche family and their close friends.
His dad gave him the serial numbers of 10 of the 11 916's made: "9142330011 to 9142330020. Most cars have survived, probably the one of his colleague got seriously damaged and wasn‘t built up again.
He (his dad) said he thinks there were possibly more prototypes with powerful engines from race Porsches (908 etc.) but they may have switched engines on the same chassis. Maybe only „Brutus“ remained."
Might be useless information, but maybe someone here can use it.
Any member here who has a 916?
