Every number on this page comes from real pre-purchase inspections — cars people were about to buy and paid an independent inspector to go through point by point, engine to underbody, paint depth to error codes. Not owner surveys, not warranty statistics, not forum lore: what we actually found.

How long does a Prius stay good?
Good cars by mileage
Good cars by age
Share of Toyota Prius models 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
Do not treat a repainted panel as a deal-breaker; respray is ordinary on these cars and structural repair is uncommon, so the body is rarely why you should walk. Start with the engine bay and a code scan: oil leaks and active error codes each turn up on 36% of them, which is enough to check both before you negotiate. Tires, shocks, and lights are the next pass — worn rubber, leaking dampers, or dead bulbs are fair reasons to cut the price, and together they signal neglect. If the scan is lit or oil is actively leaking and the ask does not move, leave it.
