How the MG ZR holds up with age
Every car fails the MOT more often as it gets older. What matters when you are buying is how steeply that happens for this particular model. These are the 2025 pass rates for the MG ZR grouped by the vehicle's age at the time of the test.
| Age at test | Tests | Pass rate |
|---|---|---|
| 11 years and over | 1,709 | 72.62% |
Why the MG ZR fails its MOT
Across every MG ZR that failed its 2025 MOT, the most common area of failure was lamps, reflectors and electrical equipment, accounting for 23.98% of all recorded failure items. These are the areas worth having checked before you buy, and worth budgeting for on an older example.

|---|---|---|
| Lamps, reflectors and electrical equipment | 23.98% | 372 |
| Brakes | 16.96% | 263 |

What this means when buying a used MG ZR
A pass rate is a population average, not a verdict on the specific car in front of you. The average MG ZR came to its 2025 test at 84,836 miles and 21.4 years old. Most examples tested were petrol.
The useful check is the individual car's own MOT record: how many times it has failed, what for, and whether advisories keep reappearing. A recurring advisory on corrosion, suspension or brakes tells you far more than a model-wide average, and a mileage that does not move consistently between tests is a warning in itself.
