According to a November 16 "Motor Trend" article, "we're told a six-passenger Gravity with second-row captain's chairs is being considered for later on."
I was planning on a Dream Edition with the captains chairs. Is it possible the top trim Gravity won't offer them . . . or that they might never arrive? (Back when we were speculating about power-operated doors in the Air, some Design Studios told people that power-operated doors were not ready for the time Dream Edition production start but would come later. They never did. One service tech even told me you could tell which Air had the power-operated doors by the presence of a piston plunger in the door instead of the metal strip that caught the door when it opened.)
And remember the "executive rear seats" in the Air that were hyped endlessly prior to launch and were actually present in many of the early demo vehicles? I'm pretty sure those plans are long since on the scrap heap.
