Mercedes-Benz MOT data — common questions
Does a good Mercedes-Benz MOT pass rate mean the car is reliable?
- No. MOT pass rate is not a reliability rating. It is the share of recorded DVSA tests that passed for that Mercedes-Benz model in this 5–10 year band. It does not prove breakdowns, repair cost, or the condition of one seller’s car.
Which Mercedes-Benz models have the most MOT tests on this page?
- The four highest-volume models in this age band are A-Class (86.6% pass rate, 1.1M tests); GLA (88% pass rate, 336k tests); GLC (88.9% pass rate, 299k tests); CLA (85.1% pass rate, 213k tests). Pass rate is a test outcome, not a ranking of the most reliable car.
Is this Mercedes-Benz page a registration MOT check?
- No. This is make and model research from aggregated DVSA tests. For one vehicle, use GOV.UK MOT history. Use Compare to put two models on the same age band.
