Mercedes-Benz 420 MOT reliability

There were not enough MOT tests of Mercedes-Benz 420s in 2025 to publish reliable figures: we need at least 1,000 tests of cars aged three and over. Cars have their first MOT at three years old, so newer models appear once they reach that age. How we work out MOT figures.

Mercedes-Benz 420 safety recalls

We found no recalls for the Mercedes-Benz 420 in DVSA’s records since 1992. That does not mean none apply: DVSA sometimes records a recall under a range or chassis name we cannot match to a model. Check a specific car on GOV.UK’s vehicle recall check.

A recall applies to cars built on particular dates or with particular VINs, not to every Mercedes-Benz 420. The details come from manufacturers through DVSA, which says they may be delayed or incomplete. To check a specific car, use GOV.UK’s vehicle recall check or ask the manufacturer or a dealer. How we match recalls to models.
