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 271 complaints with NHTSA about the 2003 Ford Mustang, and it carries 6 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.

Percentile ranks against other compact cars in the catalog.
What stands behind each score for this car:
Owners have filed 271 complaints with NHTSA for this model-year, and engine and engine cooling is the most reported area with 51 of them (19%). There are 6 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 57/100 (average) from NHTSA recall campaigns and complaint density, adjusted for how many were sold so a popular model is not penalised for having more owners.
AVOIR scores its longevity 68/100, 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: be careful, because the numbers are mixed and the complaint record is worth reading before you commit. 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.
Sources: NHTSA recalls and complaints, EPA fuel economy, IIHS awards, and live market listings. A score describes a model-year, not the individual car in front of you. Get a pre-purchase inspection.
