bought my 2015 30d m sport x5 brand new cant fault it m few minor issues but all were covered by warranty, i bought the extra 2 years from bmw so had 5 years full cover, just done 70000km no issues what so ever, usually i change cars after 5 years, will keep it for 2 more years, for piece of mind have taken an extended manufactures warranty so the same as bmw from car sales for $2410 three years, as the new warranty so cant go wrong to keep it, drives great, looks great, great on fuel, would buy the next one after this, as long as you get the service plan for bmw for 5 years and extended warranty there is no reason why you cant keep the car for 5 even 6 -7 years . if not i would change it every 4- 5 years for sure .

I bought my x5 fi5 30d brand new 3 years ago have done 60,000 km have not had a single problem
I drive it every day I did buy the service package which I think was a good idea probably after the warrenty expires I will get it serviced privately as the dealers are very expensive before this car I had a 2009 x5 e70 also very good .There is something special about bmw I really enjoy the brand.

The driving experience is amazing not much noise, easy to handle and great performance. The interior in mine is cream and it looks amazing I also have great legroom and the dashboard is very fancy. This is where the bad part comes it is really expensive to maintain i.e, fuel, oil, maintenance, brakes and etc. are super costly.

Purchased a new 2016 X5 30D with M-Sport, panoramic glass roof and innovations package. Plus 5 year warranty.
Lots of cool features, great performance for a large car and very comfortable. Maybe too comfortable.
Love the active cruise control, head up display, lane departure warning, fuel economy and so much more.
Highly recommend this vehicle.
Previous car was a BMW E92 335i which was great apart from the rattly turbo waste gates.
Loved the car and the performance but the seat belt extenders were a bad design and as mentioned above, the turbos can be noisy.
