The bottom line
Lexus RX shoppers should treat the engine as the make-or-break item. Oil leaks hit more than half these cars and fuel-trim issues follow close behind, so crawl underneath and scan for codes before you even talk price. Check the tires and those cracked bushings next; they give you easy leverage to negotiate or a reason to walk if the seller won't budge. Skip any RX that already shows a dripping engine or a stack of active codes—the rest can work if you price in the mechanical work.
