The bottom line
Paint work is background noise on a GX, so don't treat a respray as a deal-breaker or a reason to slash the price. The real money is under the hood: oil leaks show up on 78 percent of them, with cooling-system issues and hydraulic steering leaks close behind. Start underneath looking for oil and power-steering fluid, then scan for live codes and check tire wear. Active leaks plus a weak cooling system is your cue to negotiate hard or walk; a dry engine bay and a clean scan are the ones worth chasing.
