First off the Returnless cougars are the ones with a better chance of fuel pump failure. The return cougars pumps didn't have as much of a problem. Alternator's are common failure on contours/cougars alike.
It was kind of hit or miss with relibility. Mine was built 5/98 and I've had no problems at all with it. Other friends of mine have had nothing but problems. It really depends. Overall though I think it's a pretty reliable car.
As with any car you buy try to make sure it wasn't abused and it will love you back
