What stands behind each score for this car:
Owners have filed 36 complaints with NHTSA for this model-year, and engine and engine cooling is the most reported area with 8 of them (22%). There is 1 recall on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 87/100 (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 81/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2003 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 71/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
