Just like the title says, this is the rear mounted pop out cupholders that come with the Model X and late 2016 and higher Model S consoles. I have retrofitted them on my refreshed Model S that did not come with them and I'm fairly certain that they should fit on most, if not all, Model S consoles. This is for the cupholders only, you will still need to acquire the lower trim, the cupholder trim, and the vent bezel for a full retrofit. $100 plus shipping.
