Source: brand figures from Brumble analysis of DVSA's 2025 MOT test year data; model figures are DS Auto Labs' own analysis of DVSA's 2025 MOT test results (all model variants included, first-time tests). Published under the Open Government Licence v3.0. Brand figure based on 1.55 million Mercedes-Benz tests; C-Class on 358,903 tests, A-Class on 363,204.

What this means

Mercedes-Benz posts a 77.0% pass rate, comfortably above the national average, based on 1.55 million tests across the 2025 test year. That places it above most mainstream volume brands, though slightly behind BMW and Audi within the premium German tier specifically.

The C-Class and A-Class, Mercedes' most commonly tested models, pass at 74.7% and 78.3% respectively: the C-Class sits a little below the brand's overall average and the A-Class a little above it, and both are above the national average. It's a reminder that even a premium badge doesn't mean every individual model matches the brand's headline figure.
