You should check on the transmission service. I have a 93 850, and one of the more expensive problems with this car is the auto tranny. Most have to be replaced. I was able to stave off replacement until 160,000 miles by flushing it with every oil change. To replace it runs around $3000. Also, the rear main seal and a/c evaporator are expensive repairs, both of which my car needs now (at 165,000). That said, it's a great car to drive. Just be sure those things have been addressed, otherwise you will be forking out big bucks routinely.
