I hemmed. Hawed. Scratched my hair off. Lost some sleep. Coming from an M3 with plush interior I was scared to not have it all. But Elon tweeted that having kids should make you reconsider having perforated seats in your X. The thing I wanted most was the lights. What my rep told me with the white interior is that the door panels and arm rest are upgraded to match since they aren't technically leather. It's done to match. Kind of a bonus. I also worried about the self presenting doors swinging open into traffic when walking up and also smacking a biker flying by. I picked every option on my X. Somehow I felt like it was a small victory to not check one of their boxes and save 4500. So there is a little less value in it if you are going with white anyways. Another side note is the front seats are heated from what I'm told. The cold package just adds heating to rear seats. And ventilated seats only work up front, though the whole car has perforated upholstery to match.
Mine arrrives in three weeks. I can confirm if I regret this decision then.
