Reliability, what owners report, and what it costs to keep.
AVOIR's read: a solid ownership case with specific caveats below.
Owners have filed 157 complaints with NHTSA about the 1994 Mercury Cougar, and it carries no recalls. These are owner allegations rather than confirmed defects, but the pattern of what people complain about is the most useful signal a used buyer has.

What stands behind each score for this car:
Owners have filed 157 complaints with NHTSA for this model-year, and power train is the most reported area with 33 of them (21%). No recalls are on record for it.
AVOIR scores its reliability 82/100 (excellent) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 79/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 1994 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: worth a look, because a solid ownership case with specific caveats below. Its overall ownership score is 70/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
