Threads like 'color indecision' illustrate that the Design Studio on teslamotors.com, while well-done, is inadequate IMO. Three views of the car exterior isn't enough, and the same goes for interior. I'm thinking a fully-rendered full screen Model S that you can rotate/zoom/move around at will, then save/share screenshots of your configuration as well, maybe even on different backgrounds. Why not? Obviously they already have the 3D model of the car ready to go! I also think this is especially important given there is no lot you can go walk around to check out the different configurations (except in Norway, that is Tesla Motors Drammen - march 27th 7:30am - YouTube). In fact I'm surprised a tool like this isn't already on the site.
