I just wanted to post a link to a site with some beautiful high resolution images of this fantastic car.
CD PANHGARD LM64 Le Mans 1964 at chez Autodrome Paris, Pagani, Ferrari, Lamborghini specialist, Cannes, Paris
Thanks to 'groar' for creating the post on the 'interesting French document'.
I had seen references to this French car having this low of a Cd ( .12 ) , yet there were some doubts that I had read from others, and I never really bothered to do any research on the car afterwards.
Now after looking at these new images, I would believe a .12 Cd would be realistic.
What a beautiful car !
