Mercedes-Benz C-Class: what MOT records show
MOT records show 78.6% of Mercedes-Benz C-Class cars pass the MOT first time, 2.6 points better than the national average for cars of the same age (76.0%). Counted from 37,418 DVSA tests on cars registered 2002–2022; a pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure.
A car with only minor defects or advisories still passes its MOT; a major or dangerous defect is a fail. Class 4 tests in Great Britain, test type NT (a normal annual test), retests excluded. A pass, or a pass with rectification at the station, counts as a first-time pass; DVSA's own initial-test measure counts a rectified pass as a failure and so reports a lower figure. Testing in Northern Ireland is run separately by the DVA under its own rules.

How the mileage figures are counted
Class 4 tests in Great Britain, test type NT (a normal annual test), retests excluded. A pass, or a pass with rectification at the station, counts as a first-time pass; DVSA's own initial-test measure counts a rectified pass as a failure and so reports a lower figure. Odometer readings below 100 or above 400,000 miles are discarded as misreadings, and cars under three years old are excluded because no MOT is yet due. Sampled from nine months of 2025 (January, February, April, May, July, August, September, October and November). Testing in Northern Ireland is run separately by the DVA under its own rules.

- Make sure the V5C logbook matches the seller and the vehicle, and ask for the service history.
