What this means when buying a used Mercedes-Benz ML
A pass rate is a population average, not a verdict on the specific car in front of you. The average Mercedes-Benz ML came to its 2025 test at 112,981 miles and 14.8 years old. Most examples tested were diesel.
The useful check is the individual car's own MOT record: how many times it has failed, what for, and whether advisories keep reappearing. A recurring advisory on corrosion, suspension or brakes tells you far more than a model-wide average, and a mileage that does not move consistently between tests is a warning in itself.
