A pass rate records whether cars met the roadworthiness standard on test day. It is not a reliability score, and part of any gap reflects how old the tested cars were.
MG6 MOT pass rate by age
The same 2025 tests split by the car's age at test.
MG6 cars aged 6 to 10 years passed 64.5% of MOT tests. For cars aged 11 years and over that fell to 61.2%, a drop of 3.3 percentage points.
| Age at test | Tests | Pass rate | vs UK average |
|---|---|---|---|
| 3 to 5 years (small sample) | 1 | 0% | 72.3 pts below |
| 6 to 10 years | 760 | 64.5% | 7.8 pts below |
| 11 years and over | 853 | 61.2% | 11.1 pts below |
That is a smaller decline than most cars show. The UK average of 72.3% covers cars of every age, so compare like with like.
