The seven scores

How it compares in its class

Percentile ranks against other midsize & large cars in the catalog.

Reliability: better than 36% of midsize & large cars
Longevity: better than 43% of midsize & large cars
Running costs: better than 61% of midsize & large cars
Value retention: better than 57% of midsize & large cars

Which of these numbers are measured

What stands behind each score for this car:

Reliability 77: from NHTSA recalls and complaints. This one is a raw count: we do not have a sales figure for this model, so a high-volume car looks worse here than it should.
Longevity 76: an estimate from powertrain and brand record. No 200,000-mile population exists for a 2005 car yet, so this is a prior, not evidence.
Maintenance 78: repair-cost data where we have it for this model, otherwise a mechanical-complexity estimate from engine size, cylinder count and drivetrain.
Safety: no score. NHTSA crash testing thins out for older vehicles and we would rather show nothing than guess.

Common questions

What goes wrong with the 2005 Mercury Sable?

Owners have filed 83 complaints with NHTSA for this model-year, and vehicle speed control is the most reported area with 31 of them (37%). There is 1 recall on record. Check any specific car against its VIN before buying.

Is the 2005 Mercury Sable reliable?

AVOIR scores its reliability 77/100 (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.

How long will a 2005 Mercury Sable last?

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 2005 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.

Should I buy a 2005 Mercury Sable?

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 68/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
