Insight summary

MG Tf is a rare model in this snapshot, with 7,603 represented vehicles and 0.02% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 75.0% from 62,133 MOT tests, with a reliability score of 58. The current pool shows an average of 60,858 miles and an average age of 20.9 years, while mature-fleet mileage is estimated at 60,860 miles. Petrol leads the fuel split, followed by other, and the most frequent defect themes are parking brake, horn not working and exhaust emissions. The practical read is that the MG Tf looks a little better than average, but still rewards careful checks on mileage and maintenance.
