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

Good cars by mileage

Share of Toyota 4Runners 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.

Paint work is common enough that a resprayed panel should not scare you off, especially since structural repairs barely appear. The bill is underneath and in the electronics: oil leaks show up on 54% of these 4Runners, with steering-fluid seepage, live fault codes, and worn tires right behind. Before you talk price, trace every wet seam at the engine and the hydraulic steering, pull codes, and check all four tires plus the lights. A dry engine and a clean scan is the one worth keeping; active leaks or any frame repair is your cue to cut the price hard or walk.
