How they score
How long do they stay good?
Good cars by mileage
▬ Genesis▬ GMC▬ all cars
Good cars by age
▬ Genesis▬ GMC▬ all cars
Share in good shape (scoring 60+/100) by mileage and by age when we inspected them (each dot ≥5 cars; a band under 20 cars follows the nearby bands, so a run above the all-cars line stays above it, and a band of 20 or more uses the rate we measured; where a band has too few cars, the line follows the trend between the bands on either side; rolled-back odometers excluded from the mileage curve). Dashed grey = all cars we check.
