reginos:

The normal Carrera S 911, even the 991 version, is a sports car with GT characteristics rather than the other way round.

Disagree.

I have driven all of those (hard) on a track less than a couple of weeks ago and it was a revelation as far as the 991 C2S is concerned.  It has definitely gone the GT way and away from a sports car.  It is too soft: the steering, the brakes, the suspension, the balance, the PDK, and it is not precise enough.  Even in full manual mode, the PDK has this undefeatable “kick down” which is annoying to say the least.  It has a great premium stereo, though – and you can order those deliciously leather-covered vents as an option.  Those looking for something that is more of a sports car made by Porsche ought to check the GT3 instead.
