Volvo 900 Series is a very rare model in this snapshot, with 2,533 represented vehicles and 0.01% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 71.6% from 21,907 MOT tests, with a reliability score of 52. The current pool shows an average of 158,973 miles and an average age of 28.9 years, while mature-fleet mileage is estimated at 158,973 miles. Petrol leads the fuel split, followed by diesel, and the most frequent defect themes are battery insecure but not likely to fall from carrier, windscreen damage and parking brake. The practical read is that the Volvo 900 Series looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
