The bottom line
High repaint rates meet engine trouble on the Lexus GS, so assume nothing until you check. Oil leaks appear on 44% of these cars, with fuel-trim and coolant problems close behind, making a leak-down test, cooling-system pressure check, and full code scan your non-negotiables before any test drive. Budget for fresh shocks too. Zero structural repairs means the bodywork is mostly cosmetic, giving you solid ground to negotiate down for seepage or cleared codes—or to walk if the seller stonewalls on records.
