I have a parts list for the Model S and Model X Premium Console inserts. The part numbers for all of the parts for both are the same, which should be proof that they are identical. And both have retractable rear cup holders. I also eyeballed both a my SC the other day and they looked the same. Anybody know for sure? The reason I ask is that ordering the parts may cost less than ordering the complete assembly, which for the S is $1,250, including installation. I can install this myself and don't need Tesla to do it, especially if it saves considerable $.
