I honestly don't like the GTR at all. It's ugly, fat, heavy, and essentially controlled by a computer. It's like you're not even driving it. The equivalent of a Range Rovers off road electronics helping you off road but only for the race track.
I had a fwd Mini Cooper S before my bmw and I NEVER drove with the traction control system on. It was more dangerous believe it or not. With my bmw, I turn it off in the snow at times. With the great tires I have on it, I enjoy the challenge driving in snow. Only until it's real bad do I leave the TCS on.
Edit: I'm talking real life here, not gran turismo. And the bmw I have is not an X drive model.
