The bottom line

On an Infiniti, start in the engine bay. Oil leaks show up on 57 percent of them, and cooling trouble is common enough that a wet motor or low coolant is your first walk-away. Check power-steering fluid and the tires next, and scan for codes. Most have at least one resprayed panel, so get a structural look before you trust the body. Condition is a mixed bag that typically slips below decent around 121,000 miles, so that is the line to negotiate hard or keep walking unless leaks and accident history both come back clean.
