Straight from recent Lexus GS reports
2013 Lexus GS · 129k mi — flagged: oil leaks, excessive pads wear, tires condition & wear. Inspected Aug 8.
2008 Lexus GS · 79k mi — flagged: low coolant / cooling system issues, fault codes recently cleared, leaking or worn shock absorbers. Inspected Jul 31.
The bottom line
With repaint rates this high and engine problems dominating the fault list, a used GS is less about crash damage and more about deferred maintenance under the hood. Nearly nine in ten cars have fresh paint yet none show structural work, so focus your check on oil leaks that hit almost half the sample, fuel-trim issues, coolant loss, and tired shocks. Demand a pre-purchase inspection that pressure-tests the cooling system and scans for cleared codes; use any seepage or active electronics faults to negotiate hard or walk away clean.
