I went with the black painted mirrors and spoiler on me and my dads cyber gray C7.
I could do with or without the mirrors but the spoiler looks great two toned on gray or silver with those black wheels.
only other aesthetic option I would say go with is the carbon interior..but you are getting 1LT and I think you need at least 2LT to option it.. to me personally the 1LT interior is a little plain and they are using real dry carbon replacement panels.. that to me is worth the 995
