Be sure to call Jim's Bug Center on St Paul Ave in Waukesha for a quote on your next service. I just got back from picking up my Jetta, after having had the timing belt and water pump replaced (60K preventive maintenance) -- total bill was $370, $225 for the belt and $145 for the pump. I had been quoted as much as $600 for replacement of the belt alone by local VW dealers, and none was less than $450, for the belt alone. Including the water pump, the dealers would have been in the neighborhood of $750.
Gotta support your local, small businesses -- especially when they save you big money. ;-)
