I have been owning the new x1 from about a year now and done 17000 kms with it. I have the sdrive x line 20d.
Pros
1) punchy 2.0 ltr diesel engine
2)very spacious for a compact luxury suv
3) perfect drive for both city commute as well as highway
Cons
1) gear box is a torque converter and not the zf that we are used to from BMW. It is tuned nicely though
2) interior plastics at a lot of places dont feel premium
3) since it is a front wheel drive it is not as sporty as the previous generation x1
Over all very satisfied with the car
