How the Mercedes-Benz CL holds up with age

Every car fails the MOT more often as it gets older. What matters when you are buying is how steeply that happens for this particular model. These are the 2025 pass rates for the Mercedes-Benz CL grouped by the vehicle's age at the time of the test.

What this means when buying a used Mercedes-Benz CL

A pass rate is a population average, not a verdict on the specific car in front of you. The average Mercedes-Benz CL came to its 2025 test at 92,636 miles and 19.1 years old. Most examples tested were petrol.

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.
