I have a silver '13 85 with the silver 21s. I think the grey 21s would look better on my combo so I am putting out a feeler to see if anyone is interested in trading. I'm in San Diego so if anyone would like to swap wheels PM or post here. The TPMS is auto sensing so its an easy swap that can be done in about 20min. My Continentals are almost new with <750 miles on them.
