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

The bottom line
Oil leaks show up on 55 percent of these RXs and fuel-trim problems aren't far behind, so start every inspection with a cold-engine check for seepage and a scan for mixture codes before you discuss money. Active electronics faults plus cracked suspension bushings mean the undercarriage and OBD data deserve equal attention; use any fresh leaks or torn bushings as hard leverage to cut the price or walk. Resprays are ordinary here while structural repairs stay rare, so don't let fresh paint distract you from the engine and electronics that actually decide if this one is a keeper.
