Insight summary
Mercedes-Benz Viano is a very rare model in this snapshot, with 4,622 represented vehicles and 0.01% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 73.3% from 37,251 MOT tests, with a reliability score of 51. The current pool shows an average of 164,944 miles and an average age of 15.2 years, while mature-fleet mileage is estimated at 165,222 miles. Diesel leads the fuel split, followed by petrol, and the most frequent defect themes are windscreen damage, parking brake and lighting. The practical read is that the Mercedes-Benz Viano looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
