Got one of those 2000 XC's too. Has not needed much as we got it a few months ago after she rolled her SUV....:-)...But the car is solid so far.
My personal set of pointers i.e just my humble opinion... Change the oil regularly 3-4K, flush the tranny (because there is no drain plug on the torque converter) once every other year and keep rotating those tires 3-4K, ALWAYS have it flatbedded if it needs to towed....You do not want the viscous coupling to get damaged...
My suggestions for boards are the same as previously mentioned
brickboard.com (Not as good as this but not bad either..use search function to narrow down what you are looking for)
(Go to repairs/maintainence section...the famous BAY13)
