What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with not working - it accounts for 27.1% of failed tests on this model.
- Then check excessively stiff or notchy and missing, the next two most common reasons.
- Age matters here: 87.59% of 3-5 year old examples pass, against 82.34% at 6-10 years - a gap of 5.3 points.
- The most common advisory is excessively stiff or notchy (7% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 4,086 miles, which is the number to compare any advert against.

| 6-10 years | 82.34% | 368 |
