Only experience I have with an X3 is this girl that I drive with to and from classes everyday has a 2008/9 with around 20k on it. Smooth ride, kind of small for an SUV but handles pretty nice and makes a good DD.
Reminds me of my E46 interior wise, but just so much smoother and comfortable. I would never own one, but Ill keep bumming rides in it daily.
