where oh where is the power steering fluid going...

I think you will find that it is difficult to find all of the leaks in
the hydraulic system of this 16 year old car. That may be why when it
starts to leak someone suggested that whoever was having the problem at
the time should replace everything; rack, pump, and hoses. That might
fix the leak ;-)

I think most of the leaking will occur when you are driving and the
components are under pressure:
- There is the famous volcano effect of the pump sucking air in through
the seals at higher rpm and pushing the air under pressure back to the
reservoir and causing it to overflow. Evidence of hydraulic fluid
leaking down the side of the reservoir would indicate this.
- If the seals in the rack are leaking then the hydraulic fluid would
fill up the rubber boot before leaking out onto the floor.
- There are many hoses and either clamped rubber hose to metal line
connections or metal to metal with copper washers to check.
- And I suppose if the diaphragm in the hydraulic bomb sprung a leak,
you could have fluid leaking out of there too.

Have fun, and if you are doing the work yourself, enjoy mechanical work,
  are getting the parts at wholesale, then there is no doubt that the
car is worth it :-)

BTW Brian, I'm guessing from your e-mail address that you are in New
Brunswick Canada. If that is the case there is a Canadian distributor of
auto parts for imported cars on the net; 'Altrom.com'. If there isn't
already a parts house in your area that deals with them, maybe you can
get your favourite to get themselves set up. You can get on the net,
look up the parts yourself, order through your parts house by part
number, then go get them after delivery.
