2002 MG ZR 1.4L Petrol · YN02 WTO

The MG ZR’s most recent MOT test on 2025-07-08 at 100,126 miles passed without defects, though this follows a history of recurring and unresolved issues. The trend over the past three years is decidedly worsening, with critical failures in 2023 (including coolant leaks, severely deteriorated CV joints, and corroded suspension components) and only partial resolution of problems in subsequent tests. The 2024 and 2025 passes suggest temporary fixes rather than sustained maintenance, as the same areas—tyres, suspension, and brake systems—continue to appear on advisories or failings. The 2023 failure alone was severe enough to warrant a structural integrity concern over the offside rear suspension mounting, indicating long-term neglect rather than incidental wear. The vehicle’s recorded mileage of 100,126 miles over 24 years averages roughly 4,172 miles annually, which is unusually low for its age. This suggests prolonged periods of inactivity rather than consistent use, a pattern that may have accelerated deterioration through moisture retention and corrosion. Notably, there is a significant gap between the 2021 test (95,308 miles) and the 2023 failure (96,190 miles), covering nearly two years with no recorded maintenance. Such extended periods without testing or servicing are concerning, as they imply potential undocumented issues or deferred repairs. A buyer should prioritise an immediate inspection of the suspension components, particularly the offside front coil springs and rear mounting points, which were flagged for corrosion in 2023 and 2021. The CV joint boots—both front and rear—have shown severe deterioration in multiple tests, posing a risk of grease leakage and joint failure. Brake systems also warrant scrutiny, with the offside front brakes binding in 2023 and tyres consistently nearing or exceeding legal limits. Underbody corrosion, particularly around the rear sill, should be assessed for structural compromise, while the coolant system’s history of leaks demands verification of the radiator, hoses, and water pump. Given the pattern of repeated advisories, even minor issues often escalate quickly in this vehicle.
