Insight summary
Mercedes-Benz A-Class is a common model in this snapshot, with 221,859 represented vehicles and 0.53% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 80.2% from 1,538,251 MOT tests, with a reliability score of 53. The current pool shows an average of 79,516 miles and an average age of 11.0 years, while mature-fleet mileage is estimated at 88,441 miles. Diesel leads the fuel split, followed by petrol, and the most frequent defect themes are windscreen damage, lighting and coil springs. The practical read is that the Mercedes-Benz A-Class looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
