Insight summary

Mercedes-Benz C is a common model in this snapshot, with 319,740 represented vehicles and 0.77% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 79.3% from 2,336,275 MOT tests, with a reliability score of 55. The current pool shows an average of 99,294 miles and an average age of 12.5 years, while mature-fleet mileage is estimated at 111,692 miles. Diesel leads the fuel split, followed by petrol, and the most frequent defect themes are windscreen damage, tyre condition and engine warning light. The practical read is that the Mercedes-Benz C looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
