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 Priuss 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
Standing in front of a Prius, treat panel repaint as background noise and do not let paint sell you the car, because structural repairs stay uncommon while the real pattern sits elsewhere. Active electronic codes and oil leaks lead the fault list together, with worn tires and leaking shocks close behind. Plug in a scanner and look under the engine before you talk money. If live codes and an oil leak are both there, and the tires or shocks are already spent, walk away or demand a hard discount rather than treating it as a cosmetic miss.
