I agree with Wolfgang's post. I have a 97 850R wagon w/ 153000 miles on it. Here are the major repairs I've done:

ABS pump (under warrnty before 50K mi)
EVAP (also under warranty, after about a year, I needed to start topping the R134a up every once and a while if I wanted A/C)
Rear main seal ($750 USD)
Driver side ball joint & a-arm (ruined a tire because it failed)

Cheap and easy, but big differences noticed:
swaybar endlinks
Turbo return line seal
Upper engine mount

I do as much maintenance that I can by myself (Timing belt, tune-ups, flushes of fluids, brakes, etc... the dealer charges are nuts and I'm cheap).

I use Mobil 1 synthettic on the AT and engine. It's a hoot to to drive because I can haul a bunch of stuff if necessary and still make people look like morons at stoplights in their pimped-up Civics.

The 17" Volans wheels are awesome, but look out for those potholes-- they ruin tires and rims quickly.

Good luck!
