Questions about VW's 15x7 Mambo wheels

I recently called my local VW dealers parts department to get the following info about VW's Mambo wheel . . . size 15x7 and available over the counter for a retail of $145. One problem, they didn't have a listing as to the wheels offset and they didn't have one there to check. If you have this five spoke 15x7 5x100 wheel on your new Golf or Jetta I would love to know the offset 35,38,42? If you are not sure if you have the wheel go to http://www.vw.com and click on commerce and then car accessories, then alloy wheels . . . the second page has the Mambo wheel.
thanks in advance to anyone that can help, Kevin
