If I did not get Alpine White (which I love and IMO, is one of the best colours on the E70 with 214 wheels and Sport Package), I would choose Platinum Gray. It is beautiful, timeless, elegant and it seems to change in different lighting and weather conditions.

For me, black and Sparkling Bronze are my last colour choices. They are not "ugly", they just do nothing for me. Deep Sea Blue is very beautiful, but blue and green historically have the worst trade in/re-sale value (if that matters to you).

I honestly think you cannot go wrong with any of the colours you are choosing. You must select the one that gives you the "I gotta have that" feeling. That is what Alpine White did for me. The same feeling with my Dark Graphite Metallic 750i and my Interlagos Blue M3 I had....upon first sight, I knew in my gut that was "The Colour". Go with your gut!!!
