I know exactly what you are going through. I just went through it myself. I loved the salsa red and the shoreline blue in person and wanted it when I purchased mine. However, the Salsa Red the dealer had in stock was with the black/gray interior which I don't like as much as the sand biege leather. Had it been the solid black LE interior, I would have been sold. And to get the blue had to be a limited, which was out of my price range. So, I went with black with biege leather.
As has been said on here, black is a classic color as is silver and the blizzard pearl. Those colors have and always will be around. Although I loved the salsa red, I was afraid that after a few years I may get tired of it, unlike the black. The silver is also a very nice color in person.
Above all else, is it worth being unique to go with a color that initially didn't grab your attention. If the BP did so, then it may be worth going that route. You can always customize with wheels/etc to make it unique if that is a concern.
