From the first air-cooled 911 (1963) until the last water-cooled 911 generations of nowadays, more than 50 years of LEGEND look down on us from the heights. In the automobile history, there are only a couple of supercars that don't need to be called by their make name: one of them is 911. You don't need to say Porsche 911. You say 911 and everybody in the whole world knows what you are talking about. If you say NINE ELEVEN, that's all said.
