Actually Porsche still distinguishes itself on the price performance side of things. Sure you can buy a Noble for less cash than a GT3 and lap faster on the track. However, where are you going to have your Noble serviced and which car do you think is going to be more reliable? There's a saying about performance cars that makes a lot of sense: pick any two: price, speed, reliability. Porsche offers a combination of these 3 things that I don't think is matched by other manufactures. The GT3 and Turbo models are faster that most cars on the planet (as well as many more expensive cars), yet are reliable enough for daily driving. If you make them more exclusive you'll destroy the initial cost and maintenance advantage that Porsche has on Ferrari. I like cars I can enjoy day in and day out. It's much more important than the things you mentioned above.
