The bottom line
A Lexus GX sitting there is likely already painted somewhere and leaking from the engine, so start by checking panels for color or texture mismatches then immediately look underneath for oil. Those leaks appear on 77 percent, often enough that you should treat a dry engine as a bonus and use any wetness or low coolant to negotiate or walk away. Scan for active error codes next, then inspect tire wear and the power-steering system for fluid leaks. If the owner will not let you check those items properly, do not buy it.
