What to know

The C-Class tests a little below Mercedes-Benz's overall brand average of 77.0%, at 74.14%, still comfortably above the national average of 72.4%. Like its direct rivals the 3 Series and A4, it's a long-standing company car favourite, which tends to mean a wide spread of prior use and mileage across the used market.

Checking a specific C-Class's mileage pattern and advisory history across its MOT record is worthwhile, particularly for diesel examples that may have covered high annual mileages as a business car.

Check a specific C-Class's MOT history, tax status, and advisories by registration number.
