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

How long does a RX stay good?
Good cars by mileage
Good cars by age
Share of Lexus RXs 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 used RX here is an engine bet, not a body bet. Repaint is common and structural repairs are rare, so a touched panel is normal and frame work is the exception worth walking from. Oil leaks show up on 55% of these cars, often alongside fuel-trim faults and active codes, so a quiet dash does not mean the powertrain is clean. Check for fresh leaks cold and run a full scan before you talk money; cleared codes are common enough that a blank readout is not comfort. Worn tires and torn bushings are leverage for a lower price. Leak plus live codes means walk.
