The issue I see is that in the X5 they are continually introducing new features, whilst that is seen as a good thing this means introducing more things that can go wrong and a model never reaches a maturity level where all the possible issues are ironed out.... so you are never buying a car which has been on the market as a complete unit for a period of time where you can say that all the bugs would be ironed out... my 2 cents anyway... I am most likely to buy an ML next time. The designed in Germany built in China mentality is wearing thin on consumers...
