I agree with the exterior HC color discussion. The "exclusive" Clubbie color will definitely make an impression if you're thinking of resale value down the road. I'm thinking anyone who has an eye on buying a previously owned Clubbie would also have an eye for the styling of it, as well. "Exclusive" styling could play better than still available colors.
As echoed earlier, you can choose PW on any Mini.
But you also have to love seeing your chosen color everyday
