Insight summary

Seat Leon is a common model in this snapshot, with 155,970 represented vehicles and 0.37% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 80.2% from 1,087,452 MOT tests, with a reliability score of 53. The current pool shows an average of 96,977 miles and an average age of 11.1 years, while mature-fleet mileage is estimated at 113,064 miles. Petrol leads the fuel split, followed by diesel, and the most frequent defect themes are windscreen damage, tyre condition and coil springs. The practical read is that the Seat Leon looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
