Insight summary

Mazda RX-8 is a very rare model in this snapshot, with 2,108 represented vehicles and 0.01% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 73.8% from 20,074 MOT tests, with a reliability score of 55. The current pool shows an average of 69,461 miles and an average age of 17.9 years, while mature-fleet mileage is estimated at 69,466 miles. Petrol leads the fuel split, followed by electric, and the most frequent defect themes are engine warning light, exhaust emissions and coil springs. The practical read is that the Mazda RX-8 looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
