I have seen many threads about performance in snow and I'm sorry if this subject has been beat to death, but I'm asking the current and past X5 owners to put in their two cents about driving in snow (your average trip to the mountains for a vacation). I assume snow tires are a requirement and you should stay out of the deep stuff.

Those Clarkson videos make the X5 and X6 look useless on anything other than dry pavement.

TIA
