The Porsche 911 has changed very little over its 40 plus years. The 911 is special because of its air cooled design and the engine in the back. It was a revolutionary design at the time. The Porsche has changed very little over the years. Its kept the air cool system until recently in 1998 when it became water cooled. The 911 has always been a great sports car through the years. Porsche has strive to perfection. 911 are very recognizable from other sports cars because they have been around so long. What I love about Porsche 911's is that they haven't become triangular like so many other sports have. The Porsche body has remained smooth and curvy. The reason Porsche has kept the same design on the car is because their customers like it. Why change a design that so many people have come to love and admire.
