South Florida, I drive in the rain all the time... I dont really have any Problems. It is just now starting to get cold, not that it gets anywhere near as clod here as it does in other parts of the US, but still, I have not seen any problems yet. This would be my first "winter" (if you can even call it that) with the turbo. But for everyone else, when it gets cold, just make sure you pay attention to what is going on with your car.
