That is exactly what BMW needed to do in term of advertizing. I myself never liked the car until my brother-in-law got one. Once I drove it and realized it felt more like a car than a truck, I started to love it.

In all honesty, now, I see myself getting one as a 2nd car once kids start coming into the picture. Normally, I would consider a 3er/A4 wagon, but they are more expensive.

Boxy, ugly, smashed?

I don't think so ...

After the facelift, I don't find anything really wrong with the X3. It's not a beauty, but it's far from ugly.

Im sorry but
YES, YEs and YES..

this car disturbs me very much

I'd agree with this statement. The first impression from the front is a bit boxy, but I think the facelift has had a positive impact on that view as well. This is a look that grows on one. This would definitely be my choice for a daily driver amongst the SUVs/SAVs in snowy/icy conditions.
It is a given that likes and dislikes are subjective, so having a car like this and someone not liking the looks of it would not bother me in the slightest.

YES, YES and YES

Please go drool over your beloved Audis. Your fanboy-ish attitude will end in a ban again if you stroll to the BMW forums....
