If you could try to find a 96 or 97 they are the best of them.If the car was well maintianed you will be finwe if you keep up the maintaince till about 300,000.It will have the typical abs module problem like most of the 850's/S70's.But now there is a company that rebuilds it cheap.Make sure the timing belt was done at 70k and make sure you keep up with the timing belt.If not will cost you about 3k to fix.Overall as long as they were maintained well you should be fine.There will always be some minor problems happens with all cars.
Also to touch on the valve tappets issue alot of people change them when the car is having a problem with oil pan o-rings and they never know it.
