Reliability, what owners report, and what it costs to keep.
AVOIR's read: running costs are the problem rather than the car itself.
Owners have filed 369 complaints with NHTSA about the 1997 Mercury Mountaineer, and it carries 7 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 369 complaints with NHTSA for this model-year, and tires is the most reported area with 160 of them (43%). There are 7 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 79/100 (good) 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 76/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 1997 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: skip unless cheap, because running costs are the problem rather than the car itself. Its overall ownership score is 66/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
