getting a 03 wolfsburg

hay every one,
i'm new here i'm going to pick up a jetta wolfsburg,
quick question, some one told me that all wolfsburg are put together and all parts come from the wolfsburg factory in germany.
but when i looked at the sicker on the car, the tranny is from argentina.
what gives?
also someone told me that the vin has to start VW if it were a wolfsburg.
is the car a "real" wolfsburg or a dealer special?
thanks
Shah
