AVOIR scores its reliability 90/100 (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 2018 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
