I am considering to buy a 2002 325IT wagon but I am concerned about maintenance cost over the next 100,000 miles or so. Right now the used car in question has only 20,000 miles on it. What are some of the milages out there on peoples' 325's and what problems have you experienced? Maintenance $$?

Service bulletins? Problems with factory claims? There is only about a year left on the factory warranty of the car in question. What can I expect as a yearly service budget for the three years following the expiration of the factory warranty?
BTW I have a 1999 VW Passat wagon that I like, and may keep.
