How long does a Corolla stay good?
Good cars by mileage
Good cars by age
Share of Toyota Corollas 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). The dashed grey curve is all cars we check.

The bottom line
A tidy Corolla can still be a leaky engine on worn tires. Repaint is common enough that fresh paint alone should not scare you off, and structural repairs are rare, so the body story is usually cosmetic. The engine is the real filter: oil leaks show up on 41% of these cars, often with fuel trim out of range and live fault codes. Get under it and scan it before you talk price. Leaks plus bad trim justify a hard negotiation or a walk-away. Tired tires are a bargaining chip, not proof the car is sound.
