I had the same worry, the graphite looks amazing when perfectly clean, dealer had one in the showroom under the spotlights and I was very tempted. My fav colour is the F sport blue but unfortunately not available on other models.
Plus my last several cars have all been blue, silver and black; I had always wanted a soul red Mazda but that option on my old gt sport 6 put my company car £2 a month over my limit, the Mesa is close enough
