I had a 2008 with auto and I hate to say but the most troublesome car I have ever owed. Xfer case went at 43k miles but was over warranty by a few months in time no goodwill on that. It appears a nylon gear engages the 4 wheel drive and it wears over time(look up triad of warnings or something like that. Pano roof broke wouldnt open or close another known issue. Oil leaks at about 60k miles never had that with any car at suchlow miles. All three were well know issues if you check the BMW forums. The lifters would tick like a car with 300k miles if driven for short trips. BMW was replacing heads at one time I chose not to have evasive surgery and just told the wife to keep it in sport, with the revs up oil would keep the lifters pumped up. Thars all I remember off the top of my head, got rid of it when it hit 100k. The biggest POS I have ever owned by far. It handled great for SUV and the inline 6 was smooth but not worth the hassle
