It will be impossible to get 0 reading. They need to drive the car from factory to the parking lot and later to the delivery truck at the least. For US bound car, it will be an additional port from and port to. VPC check and another parking and trucking. Of course the dealer will do some test drive.
At the least, the main odometer reading will say 0 but the trip display will say 0.5 or less. My 2 ED readings are 0.4 and 0.5. But it will show 0 on the odo.
