Fun to drive but...
 This is a well-equipped small luxury SUV or SAV as BMW calls it.  Fun to drive, easy to park, easy to load and unload groceries from the rear tailgate and there-in lies the problem.  The rear lift door develops a rattle and needs adjustment by the service department frequently.  My 2016 X3 has only 10K miles and has needed this adjustment twice in the last ninety days.  Service adviser said it is apparently  a design flaw and they are seeing the problem regularly.  For a vehicle that is marketed for it's quiet interior, this was very disturbing.  Love almost everything about this vehicle but the constant rattle from the rear lift door is extremely annoying.
