I am thinking that the report he is talking about is the HVBoM or OASIS report which is helpful to find out items about your car. As for the "Real" build sheets you may have better lucl winning the lotto than ever finding this. I have heard stories of people finding them in the glove box, under the carpet, inside the seats, under the back seat or even in the trunk. I have a '07 GT/CS and I have not found anything. If there ever was any paper work from the factory it may have been throw out during the dealerships PDI.
