Wait. There are multiple pictures posted here recently of people who have picked up their P3D Stealth, and they DO have Track Mode (pictures posted!).
The bigger question is if they keep the track mode. It's not uncommon for Tesla to ship vehicles with the wrong options - e.g; SR owners got SR+ options for months before it was reversed.
Best bet is to confirm what the stealth P3Ds come with before buying, or you could be banking on options you don't get to keep. Not easy, I know, since sales folk tend to know about as much as we do.
