The 911 has been the quintessential Porsche since 1964. Although it hasn't changed much in its classic proportions and appearance, the current generation that bowed in 1999 is among the only true sports cars that can serve as a daily driver as well. The 911's handling is agile and much more forgiving than previous incarnations of the car.
