Source: DS Auto Labs analysis of DVSA's anonymised 2025 MOT test results (Open Government Licence v3.0): 63,765 first-time tests of MG ZS cars of all ages (test class 4, cars and light vans). A pass means a clean first-time pass; a car that failed and was repaired at the test station before passing counts as not passed, and aborted tests are excluded. Age is the car's age at the 2025 test.
What to know
In 2025, MG ZS cars passed their MOT first time 82.1% of the time, across 63,765 tests. That is 1.3 points above MG's overall brand average of 80.8% and 9.7 points above the national average of 72.4%.
Age explains much of the difference between models. Pass rates fall steeply as cars get older, for every make, so a model with many old cars on the road looks worse than it is, and a recent model looks better. This compares the MG ZS with the typical UK car of the same age.
| Car age | MG ZS | All UK cars | Tests |
|---|---|---|---|
| 3-5 years | 84.6% | 87.2% | 46,432 |
| 6-9 years | 75.0% | 79.3% | 14,123 |
| 14+ years | 59.3% | 59.3% | 1,061 |
Allowing for the age mix of the cars tested, a typical UK car would be expected to pass about 85.2% of the time. The MG ZS passed at 82.1%, which is 3.1 points below that expected rate.
