I have no basis for saying this, but I think the P1 is going to be a special driving car.  I was not a 12C fan at all until I drove it and I realized that McLaren had achieved some special results.  If the P1 can have 12C road performance but GT3 class track performance, than that is a special achievement.  Time will tell, if it is that special of a driving car than the rest of the cars will sell out.  if it is not it will be a real embarrassment for Mclaren getting the program wrong
