Got to test drive a Model X in Raleigh, NC yesterday. The driving experience was phenomenal! The front row is very comfortable and spacious. I'm a big guy at 6'4" and 280+, with a long back (only 34" inseam). I had plenty of headroom and legroom, and loved the unobstructed view through the expansive windshield. We've ordered the 6-seat config, knowing that the 3rd row seats would be tight, and used infrequently. Even so the room in the 3rd row was a bit disappointing, but tolerable. The 2nd row seats are quite comfortable, and when pushed all the way back the leg room is good. Head room is also pretty good, thanks to the windows above. Would like the ability to tilt back a bit more. The arm rests molded into the doors are nice, but we missed not having any on the opposite side of the seat. The big problem is that the seats are positioned too far to the outside, so when the Falcon Wing Doors are closed it is quite cramped on one side. For me it is very uncomfortable. My 5'10" son felt cramped. My 5'7" daughter did not feel cramped. Moving the seats 1 or 2 inches toward the middle would make a huge difference. I really hope there's eventually a way to do that. I can imagine 2 ways to accomplish it: An off-center connection in the mounting bracket on the bottom of the seat to the monopost. Am offset bend in the monopost. Something like this: Have to be careful not to move them too much as then the middle edge of the skylight might interfere with head room.
