Straight from recent Lexus RX reports

The bottom line
Expect engine trouble first. Oil leaks hit 55 percent of these, frequently alongside fuel trim problems and live error codes, so a flashlight under the motor and a scan are non-negotiable before you bid. Then look at the tires and the suspension bushings; those wear items are common and fair game to knock the price. Don't spook at a respray by itself, but if leaks, codes, and torn bushings pile up on the same car, walk away. Condition runs the full range from excellent to poor, so this one has to earn it on its own.
