it was just an upgraded trim line.   they sold them from the beginning model
year, as with all worlfsburgs..  i dont think vw is currently offering any
'01 wolfsburg models, but my friend has a '98 Jetta3 wolfsburg..

Chris, they sure are.  I saw a Jetta 1.8T today on a dealer's lot in Atlanta with BBS RX type wheels, and the Wolfsburg badge below the side marker signal.
