Insight summary
Mercedes-Benz X is a very rare model in this snapshot, with 3,694 represented vehicles and 0.01% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 83.2% from 21,893 MOT tests, with a reliability score of 49. The current pool shows an average of 71,729 miles and an average age of 6.4 years. Diesel leads the fuel split, and the most frequent defect themes are engine warning light, parking brake and lighting. The practical read is that the Mercedes-Benz X looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
