Our dealership: Car is removed from the shipping vehicle, checked in. A technician does the initial PDI (pre-delivery inspection), and if the car has been ordered, does the PDI 1 and 2. Every system on the car is supposed to be checked as per a check sheet BMW prints out. The car, after being inspected, has different options added to it as per customer request. Example (cd changers, phones, garage door openers, alarms, etc..) Also the car/key memory is programmed, fault memory is read, and the car sometimes is test driven (99% of the time not). Also in this state, state inspections are required, so the tech state inspects the car. The tech then hands the keys to the porters who fill your car w/fuel, and then proceed to wash, polish, buff, clean every single visible part of your vehicle.
