Yep. The M-Sport exterior trim is tricky ... massive front bumpers in full body color, whell arches & rocker panels in body color etc. In some color cases the X4 looks a bit too heavy. Eg. IMHO the best looking trim is the X-Line - featuring black parts + alu parts - so the look is less monotone.
Couldn't agree more here the X-Line is great and would have been my choice for the wife's X1 but she preferred the patterned cloth seats of the Sport though it too has black trim to lift the design, as for the M/Sport I particularly any of them regardless of model in Space Grey as it's dark enough to highlight the curves and creases in the design but not too dark to lose the finer details but they do need to change their policy of everything painted body colour.
X4 also needs (it's mandatory for the car to looks superb) biggest wheels & LED headlights (much sharper & much more aggressive graphics).
The "problem" with such stylish BMW models is they are also usually offered in base "pedestrian" versions: with small wheels, halogen headlights etc
Every manufacturer does this, IMO it's their way of making their cars appear cheaper than how the vast majority leave the showrooms but it's a great way of earning extra cash as the price of optional extras far exceed they cost.
