Went from Nissan 200 SX to '03 996 C4S.
I only have one car at a time, so it gets driven every day in all weathers, plus also for work.
It has a lot more traction the the Nissan, is faster, but goes sideways less often, which is a feature of the big tyres and lack of ability to get to the speeds where is loses grip in safety on the public highway. I also haven't quite figured out exactly how PSM will behave under various levels of abuse and road conditions. I have considered turning it off so that then at least I will be in complete control (or lack of it). I have managed to slide it quite well even when it was on.
As an ownership proposition, I have no real complaints. It is warm (electric seats), safe (with ABS, PSM, etc. when tired), quick enough to seriously jeopardise my licence and possibly freedom.
There are times I think it a bit too accomplished, since it seems to just take everything in its stride. More mid range grunt would be good, but I guess a Turbo is required (and some more saving is required first). However, I spend just about all my time 98%(?) staring at the back end of another vehicle, since empty stretches of road just aren't long enough before you catch the next car.
On the styling front, I really like it. Originally I was not sure about the headlights, but they are quite practical and I am not sure where they will put the washers on the 997. It grows on you as well. I prefer the fat arsed look of the C4S, but I don't think I am unique in this judging by the sales.
I would question why you want to change though. What is it you are looking for?
