Watch the video @ 6:40 and then again, at 12:40. Every car gets driven. My car had 18 miles it when it came off the truck, 24 by the time the paperwork was completed, and I hadn't even driven it yet. . G82s come from the Dingolfing Plant, and G80s come from the Munich plant, so they have different test tracks.
My car, just like ChicagoFans, was at the Oxnard port, in SoCal. The cars are taken off the RORO (Roll on Roll off, ship) and driven to the VPC. The VPC by map is at least a 1/4-1/2 a mile from the port. Then it gets to the yard, and moved around. My car was parked in 5 different bays before the stop sale was completed, and it was loaded on the truck, for delivery.
