Was your 60K mile service performed on schedule?  This is the sort of
thing that they should have caught.

They're right, the service manual says that they should check the
condition of all belts every 30K miles and replace if necessary. 
Generally the timing belt, water pump, and all tensioners are generally
replaced at 60K miles.  It's unlikely (though possible) that the timing
belt will last much longer than 60K miles, especially considering that
the water pumps in the earlier V6's tend to seize with little warning. 
Given that my guess is that your dealer was somewhat negligent in
servicing your car.

The water pump on the V6 will by no means last indefinetely, mine was
replaced (along with timing belt, tensioners, and a number of engine
seals) at about 45K miles.  Many water pumps don't even last that long,
and if your dealer was competant at all they would have replaced all of
this at the 60K mile service.
If you have a *very* good relationship with your dealer, I would talk to
them and see if they will pick up any of the repairs themselves.  You
can be pretty sure that AoA won't be of much help.  Ask your dealer why
they didn't change the belt and water pump at the 60K mile service, tell
them that if they're worth anything they would know that the water pumps
are prone to seizing and that they should know that the timing belts
should probably be replaced at 60K miles regardless of what they look
like.  Threatening to take the problem to a higher-order representative
is a largely symbolic gesture because everyone knows that it probably
won't get you much.  Do it anyway, it shows that you care enough to try.
If they agree to pick up some/all of the tab for the repairs, let them
do it and find yourself a new dealer to do your work from now on.  If
they don't agree to pay for anything, find a new dealer to do the work
and have your car taken there for the work.

Good luck!

That's not all; we're supposed to believe that Tony Danza sitcoms
threaten to bring Western Civilization crashing down amid anguished
cries of *Wer ist hier der Boss*?
