New x3 owner

[04X3]

Hey guys,

So I just got a 2004 x3 with about 55,000 miles on it. It's been maintained and serviced regularly, and it came with the navigation.

I just wanted to know if there's anything a new x3 owner should be careful about. I know the panoramic sunroofs had problems, but I don't use the panorama feature on mine anyway.
Do you guys have any advice for a new x3 owner?

The transmission is a little rough, I don't know if I should change the transmission fluid (never been changed), because the dealer says not to.

Also, the car will be in cold, wintery weather in a few months time. Anything I should do to the car to prepare it for snow and the cold winter up north?



thanks in advance,
