Insight summary

Infiniti Q50 is a very rare model in this snapshot, with 2,208 represented vehicles and 0.01% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 81.9% from 15,189 MOT tests, with a reliability score of 52. The current pool shows an average of 87,165 miles and an average age of 9.4 years, while mature-fleet mileage is estimated at 92,189 miles. Diesel leads the fuel split, followed by petrol, and the most frequent defect themes are brake pads, windscreen damage and tyre condition. The practical read is that the Infiniti Q50 looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
