Based on 294 used Lexus vehicles we inspected, they are in about average shape — average condition 60/100 vs 61 for all cars we check. Every number on this page comes from real pre-purchase inspections — cars people were about to buy and paid an independent inspector to go through point by point, engine to underbody, paint depth to error codes. Not owner surveys, not warranty statistics, not forum lore: what we actually found.

The bottom line

The pattern here is an engine that weeps and a body that's almost always been painted. Oil leaks show up on more than half of these cars, with fuel trim and coolant issues right behind, so put it on a lift first. Skip 2012–14; aim for 2015 and newer, especially 2018–20. They typically stay decent until about 126,000 miles, so a later car with a dry bay is the smart buy. Use the repaint and any seepage or error codes to knock the price, and walk if the cooling system is already struggling.
