I was thinking the other day how much cooler it would be to have "color keyed" door handles on the Model S. Perhaps just the outside face, leaving it chrome on the inner handle/grip areas. This way the whole side of the car would look flush, maybe just a touch more futuristic, with no chrome call-outs for the handles. Then I started to wonder about other third party mods one might want to make to their Model S. Not that I'd want to trash the great design Franz and team have created here. I.e. the last thing I'd want to see is some ridiculous 8" high wing on the back by some hack. I know they're developing see through, flexible solar cells that can be attached to glass. When the technology is ready, I'd love to see some solar capture with this applied to the roof. In theory you could apply it too any of the roof tops, pano, black, or colored. What suggestions would you have for post-market add-ons?
