The timing belt/water pump interval for the early gen cars is 6 years or 90k miles whichever comes first - like a warranty. So if this hasn't been done, actually should already be on its second replacement belt, then it needs that service. I would consider very strongly the 60k service as well which should include many other things like all fluids. I would also consider replacing all the coolant hoses but short of all of them there are 4 primary hoses that should be changed. At this age I'd probably do all of them.
If there is anything you need to keep up with these are the biggies. The engine is aluminum and if any coolant hoses go, well, it could mean warpage to the heads - really not good and very expensive to fix. No need to take that risk as well as the timing belt - it is catastrophic if that belt fails as you may know.
That's about it and happy motoring. You should surely enjoy the car. How bout some pics? Love to see it. Good luck,
