The bottom line
The GX story is heavy bodywork plus chronic engine leaks, so approach every example as a negotiation from the start. With repaints on 92 percent of them you begin by checking panel gaps and paint thickness before anything else. Then get underneath for the oil leaks that show up constantly, plus coolant and steering fluid seepage, active error codes, and tired rubber. Insist on a dry underside and clean electronics scan or walk—only a leak-free, honestly maintained one earns full price.
