That is not the point of a sports car. There are many GTs faster than purist sports cars, but the sports car driving experience is entirely different than a GT's. In the latest C&D lightning lap, the Panamera spanked many sports cars, and in one of the turns carried a minimum speed second only to a relatively exotic car, but someone looking for a sports car still wouldn't buy it. An E92 M3 is a numb driving experience compared to a 911.
many think the 911 is fugly, an expedient solution made by Dr. Ing. (hc) F. Porsche so he could sell all the VW bug chassis he had lying around
Sure, so did I, but the rear engine config does have its unique advantages: the gearbox and drive axles are close to the engine minimizing losses, and there is somewhat usable rear seating. The backwards weight distribution helps with standing starts, and lets the car apply more braking power to the rear wheels. And one cannot deny that Porsche has made the rear-engine packaging into one of the fastest, most reliable race cars available, and they're built on the same assembly line as the regular cars. In comparison, the very impressive M3s raced in ALMS are essentially spaceframe racecars with an M3 skin, and a few token pieces of interior trim.
