2019 MG ZS MOT pass rate: 83.1% (23,583 tests)
Is the 2019 ZS getting worse?
Pass rate of 2019-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 86.2% -3.6 vs same-age |
|
| 2024 | 83.3% -5.1 vs same-age |
|
| 2025 | 79.8% -7.2 vs same-age |
The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

FAQs
Is a 2019 MG ZS reliable?

What mileage is too high for a 2019 ZS?
The median tested example shows 31,565 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
