I have had my Probe for just on 2.5 years now and bought it with 86,000km on the clock (it now has just under 163,000km) . I would have to agree with Craig that the only bad point about about the car is any genuine parts or even the odd service is going to cost a lot.
About 6 months after I got my car I had the 100,000km service to perfom (very major service). Went to the Ford dealer who I purchased the car from to have the service done. I was origionaly quoted between $600-$700 for the complete service. Anyway to cut a long story short and 4 trips back to the dealer to get things fixed that werent faulty before the car went in for the service and I had parted with over $1100.... :-( for one service. (NOT HAPPY JAN)
Needless to say I do as much of the servicing as I can. One of the main things that the engine need is a clean supply of Mobil 1 to keep all the cams and lifter quiet, and apart from normal maintanence that you would have with any car its been fine.
