Porsche is to dream cars what Jimmy Choo is to shoes. So, when a car comes along, and it’s the fastest road-going sports car ever built in the company’s history, it just has to be something special. The 911 GT2 RS is just such a car. Its performance is mind-boggling: it has a top speed of 330 km/h and scampers from zero to 100 km/h in just 3.4 seconds. Want one? Alas, only 500 were produced late last year, and they were sold out within weeks. Which means it’s like a miracle cure for cellulite. Unattainable.
