This is a dilemma I hope to be going through in a couple of years time so I will be interested to read what your decision is. Though I haven't driven a 997C2S I have driven a 996 C2S and been a passenger in a 996 turbo and i'm afraid, as un-biased as I am trying to be I anticipate the sheer exhilaration of the 996 turbo will win hands down. No doubt the purists will tell you it doesn't have the delicate 'feel' of a 2wd car, well that may be true on the odd occasion it visits a track, but I suspect it wont be an issue for me (and probably most fi they are really really honest with themselves) where the car would spend 99% of its time - on the road. The 996 turbo is not exactly lacking in the feel department. As for 'laggy' turbocharged cars - well think of it this way - an N/A car just has infinate turbo lag - I know for a fact that a 996 turbo is no slouch for the very very short time it is off boost, and when the boost comes on it is like being on the bridge of the Starship Enterprise when going to warp factor 5 (I imagine) - it is almost 997C2S perfomance off boost, and being caterpulted off a Medeivel siege machine when the boost comes in. Anyway there is a foolproof solution for turbolag if it really bothers you. It is called a gear stick. You need to adapt your driving style for a turbocharged car. I never found turbo lag to be an issue in the 944 turbo unless I was in a really really lazy mood - and I mean so lazy even breathing seemed like an effort, and the turbo lag in 944 turbo's is measured in Aeons and not seconds. And in fact I found the lag made me a better driver as I had to constantly anticipate and plan ahead and I developed a very deft right foot to control the surge of power when it did come in. But like they say, best to extensively drive both, these things are pretty personal to the lucky person with the dilemma. Good Luck!
