Ask for a certificate of authenticity from Porsche (essentially the OEM build specs with all options as originally ordered). The Vin # is on the dash driver side behind the windshield). The engine number is near the base of the fan shroud in the engine. There is a book called the Porsche 911 Engine History and Development by Tobias Aichele (probably at the local Barnes & Noble or Border Books) which contains the series engine numbers for different model years that you can check for reasonable correctness.
