2016 MG Gs MOT pass rate: 80.8% (1,688 tests)
Is the 2016 Gs getting worse?
Pass rate of 2016-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 84.8% +1.6 vs same-age |
|
| 2024 | 80.7% -0.5 vs same-age |
|
| 2025 | 76.8% -2.8 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.

What mileage is too high for a 2016 Gs?
