What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with missing - it accounts for 47.4% of failed tests on this model.
- Then check insecure and too high, the next two most common reasons.
- The most common advisory is has a major leak of exhaust gases (4.6% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 35,320 miles, which is the number to compare any advert against.
Pass rate by age
A single pass rate hides the most useful thing in this data: how the same model behaves at three years old and at fifteen.
| Age at test | Pass rate | Tests | |
|---|---|---|---|
| 16+ years | 81.4% | 215 |
