I know I sure have been enjoying the AWD in my 328xi coupe all week in this rain we've been having in NJ. My old M3 would have been all over the road with the water filled ruts. In the dry, I don't even really notice that it's AWD. I am hoping that it's at least as stable as my X-3 in the winter too.
