1991 Coupe Quattro about to leave warranty

[jsala@mercury.uah.ualberta.ca (Jon Sala)]

My 91 Coupe is about to cross the 100K line and use up its warranty. I'm
planning to take the car in to the local dealer for a couple of minor things
(front washer pump quit), an occasional low speed grating noise from the
rear (which I suspect may be the disks), and the tranny has on a couple of
widely separated instances made a bit of a growl while coasting in 2nd gear.

I bought the car earlier this year, and have had no appreciable trouble with
it. According to the mechanic has been a virtually trouble free car. 

Can someone give me some advice on how to best handle this transition?
