The mileage windows when the 2002 Mercedes-Benz G-Class most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
At this mileage, the G-Class is generally still quite new and robust. The primary concerns are usually minor, often related to initial quirks or early electrical gremlins that can be addressed under warranty.
Maintenance Zone
