The bottom line
These GXs mostly hover in mediocre territory, driven by almost every example carrying repainted panels and oil leaks that show up constantly. Prioritize a thorough under-hood check for seepage and low coolant before anything else, then verify power-steering fluid and pull any active codes. With repaints on 92 percent of them, treat the body as previously worked and hunt for poor blend work; lean on visible leaks or tired tires to negotiate hard, and walk if the engine is already weeping oil heavily.
