They didn't say what they have done to the PDK. The PDK can be come a problem over 580/600 BHP as time and power takes its toll. Its has 2 clutches inside and can suffer similar but not related problems as Tip boxes do..
Got a 996tt but I was looking at the Turbo last weekend ( 4 doors is a big plus to me) but still way out my price bracket. Will have to stick with the 996.

 

if i was to take LSD and "pimp my ride" it would look something like this car!
