If you want to feel the power I'd suggest shopping for a Turbo model.
I have a '95 854T (sedan) and have always appreciated the feeling of power.
Mine has about 120,000 miles on it, and I bought it with 12,000 miles on it. There were lots of little issues with the 850...many of which were covered under warranty. The common problems over 80,000 miles would be the A/C evaporator, automatic transmission, intermittent starting problems, rear and main seal oil leaks, motor mounts, shocks/struts, oxygen sensors, CV boots, knock sensor, head liner...
If you want a car without as many 'issues' you may want to try a Toyota.

I had the transmission flushed about 10,000 miles ago. I need both an A/C evap and probably a condensor. I had been recharging for a couple of years but now that doesn't work. I live in Florida so we use the A/C a lot, so if the car was in a warmer climate I'd be sure that at 91,000 miles it'd probably need an evap. if it hasn't already been replaced.
They can mask that by having it charged while trying to sell it.
