Stopped by the local Tesla showroom today as my wife wanted to check out the X after our order for the S was confirmed. Still think the S is the better car for us, but as others have stated in here, the X definitely feels closer to the $100k+ price tag. A few examples: 1. Soft touch materials on door frames are noticeably softer and more premium-feeling on X. 2. Perforated seats with adjustable headrests on X feel and look nicer than the next gen S seats 3. Rubber door seals on X are clearly manufactured from a different and harder material than on the S, making them feel much sturdier and less prone to getting folded underneath the door frame. 4. Closing door on X by stepping on the brakes is pretty neat. Having to manually close doors on S feels a little outdated in comparison. 5. Soft close doors! Why aren't these on the S too? 6. Integrated center console has wood on the main sliding panel. S just has the typical soft touch stuff. Since it seems that a lot of the parts would be interchangeable with the X, one can only hope that eventually the S will see similar upgrades.
