Actually with my '17 MS I have FSDb, free super-charging as long as I own it, premium cellular service for life, and no interior camera. Not sure if this quite qualifies as a "unicorn car" just yet but I actually prefer this configuration over what is rolling off the floor today.
Of course, it's not really "free" - I paid for all of that in spades, back when we "saved Tesla" and since Elon has pretty much abandoned us. But still, I'm thinking 1) I'll keep this untl the wheels fall off, and 2) if I do need to sell, someone would pay a premium for such a config. Maybe not, but I'd like to think so. I'm also glad to have the 100 kWh battery to help cover degradation.
