Reliability, what owners report, and what it costs to keep.
AVOIR's read: the numbers are mixed and the complaint record is worth reading before you commit.
Owners have filed 75 complaints with NHTSA about the 1996 Mercury Cougar, and it carries 2 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.

NHTSA lists 2 recall campaigns for the 1996 Mercury Cougar. Recalls are free to have fixed at a franchised dealer regardless of who owns the car now, but only if they were never done, so check the VIN of the specific car rather than trusting the model.
WHEN IN THE SECONDARY LATCHED POSITION, THE DRIVER DOOR LATCHES MAY OPEN WHEN SUBJECTED TO TRANSVERSE LOADS LESS THAN THAT SPECIFIED IN FMVSS NO. 206, "DOOR LOCKS AND DOOR RETENTION COMPONENTS."
Risk: THE DRIVER'S DOOR, WHEN CLOSED ONLY TO THE SECONDARY LATCHED POSITION, MAY NOT SUSTAIN A 1,000 POUND TRANSVERSE LOAD.
Fix: DEALERS WILL INSPECT AND, IF NECESSARY, REPLACE THE DRIVER DOOR LATCH.
UNDER CERTAIN CONDITIONS, THE CLIMATE CONTROL BLOWER DOES NOT OPERATE AS INTENDED. THE BLOWER COULD (1) STICK ON "HIGH;" (2) OPERATE ERRATICALLY WITH BLOWER OUTPUT VARYING BETWEEN NO BLOWER AND MAXIMUM BLOWER; OR (3) NOT OPERATE AT ALL DUE TO MALFUNCTION OF THE TEMPERATURE CONTROL MODULE.
Risk: BLOWER MALFUNCTIONS LIMITING OR STOPPING OUTPUT CAN ADVERSELY AFFECT WINDSHIELD DEFROSTING AND DEFOGGING PERFORMANCE INCREASING THE POTENTIAL FOR A VEHICLE ACCIDENT.
Fix: DEALERS WILL REPLACE THE SEMI-AUTOMATIC TEMPERATURE CONTROL MODULES WITH MODULES CONTAINING REVISED SOFTWARE.

What stands behind each score for this car:
Owners have filed 75 complaints with NHTSA for this model-year, and engine and engine cooling is the most reported area with 19 of them (25%). There are 2 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 81/100 (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 78/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 1996 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: be careful, because the numbers are mixed and the complaint record is worth reading before you commit. Its overall ownership score is 69/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
