While growing up, two features really stood out when I started dreaming about what I might someday get to drive. Popup headlights (which I first enjoyed in my mom's '88 Celica and eventually with my NSX) and gullwing doors (thanks, in part, to Back to the Future's use of the DeLorean DMC-12, but also fueled by my love for the Mercedes 300SL). The Model X's Falcon Wings are next level given their hinged-approach and ability to sense and adapt to their surroundings.
A silver one prepares to leave as a titanium one enters the lot...the latter appears to be the one I'll get to drive
