Here are my 20" 214s in black, I was basically looking at several of the same wheels you were and i was going to use the 214s for winter but I find so many of my friends love the 214s I am going to stick with them. I am going to get 20-25mm spacers for the rear and maybe 10-15mm for the front.
How ever if I didnt have the 214s and I was looking to buy something I think skunks set up is more the direction I would look or the 299style. I am a wide tire lover my car has 275/305mm but for some reason I have no inclination to go 295/335 on the X5??? It looks good but maybe I am getting cheap in my old age.
