X3 will withstand anything short of a nuclear blast. I've taken it off-roading (not hardcore off-roading, but not easy stuff either), through a foot of standing water, a hot 100F day with AC on in traffic, and torrential downpours. This winter, it'll see a few days of Canadian winter. And White05X3 has proven it on the track (Can't wait till the BMW-sponsored event on sunday). When you think about it, no other SUV in its price range does everything quite as well. Oh and of course, nothing sounds quite as good either.
