Insight summary

MG Zr is a very rare model in this snapshot, with 1,458 represented vehicles and 0.00% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 71.4% from 15,041 MOT tests, with a reliability score of 52. The current pool shows an average of 88,998 miles and an average age of 20.2 years, while mature-fleet mileage is estimated at 88,998 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, driveshaft boots and windscreen damage. The practical read is that the MG Zr looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
