The bottom line
Almost every GS we see has been resprayed, so a shiny panel is not a clean history — but none of these cars showed structural repair, which means the paint story is usually cosmetic rather than crash damage. The real money is under the hood: oil leaks, fuel trim, and cooling problems cluster together, with tired shocks right behind them. On the car in front of you, start with a cold leak check, a scan for fuel-trim and active codes, and a bounce test on the dampers. One isolated leak is a negotiation chip; leaks plus low coolant plus codes is a walk-away unless the seller prices the engine work in.
