I've had my Model S 70 for a little over a month and have been pretty happy with the car (though I did have an issue on delivery where the door would pop open every time I unlocked the car). I've always thought the seatbelt "felt funny", so today I compared it to the passenger side, and what do you know? It's installed the wrong way! I'll call tomorrow to make an appointment for this, as well as the driver's side seat being loose (it "clunks" when you move around, hit a speed bump, etc).
It might be worth making sure all of yours are facing the right way!
