What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with missing - it accounts for 48.4% of failed tests on this model.
- Then check excessively binding and not working, the next two most common reasons.
- The most common advisory is excessively loose (6.3% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 11,416 miles, which is the number to compare any advert against.
Pass rate by age

| Age at test | Pass rate | Tests | |
|---|---|---|---|
| 3-5 years | 73.9% | 364 | |
| 6-10 years | 75.52% | 143 |
