Not owner surveys, not warranty statistics, not forum lore: what we actually found.

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 is still an engine car more than a body car. A resprayed panel is ordinary here and structural repairs stay rare, so paint alone is not a reason to walk. Put the first money into a cold engine: oil leaks lead the fault list, and fuel trim out of range is common enough to scan live before you trust a quiet dash. Worn tires and a TPMS fault are negotiation items. Active codes still show on about one in five cars, so a dry engine plus a clean scan is the car worth paying for; oil on the belly and bad trims means cut the price hard or leave.
