I searched for and found silver/black stripes, wouldn't accept anything else and just love the color. Subtle and relatively understated (I even changed the red calipers for gray) yet sexy and well defined. As far as the production volume is concerned, indeed silver is the rarest (fewer yellow in 05, but yellow continued into 06, silver did not). Why so few? Well IMO it didn't have to do with real time popularity since at the time the cars were priced well over sticker and all colors were selling slowly. I'd guess the production volumes were set by Ford Marketing applying God only knows what criteria. I hear that silver is the preferred color for any sports car in the UK. Is that true?
