I bought a car that was in stock - unfortunately it does not have DD Pro. From your description of the mirrors, I suspect that I will also be able to just squeeze the car through the door.
I have a garage with 2 relatively narrow doors. The Model S that I am replacing can fit in the doors (barely) if I fold the mirrors in. The specs of the air indicate "Width (with/without mirrors) in 86.4 / 76.2"
Does the without measurment mean the width when the mirrors are folded in, or is...
