When it starts failing
At 100–120k miles this one fails 12% of its inspections, against the 23% an ordinary car of the same age fails.
| Odometer | Failure rate | Rate | Its age | Tests |
|---|---|---|---|---|
| 40–60k miles | 8% | — | 49 | |
| 60–80k miles | 19% | 23% | 73 | |
| 80–100k miles | 15% | 25% | 68 | |

| 120–140k miles | 13% | — | 55 |
287 British inspections, grouped by the odometer reading recorded at the test.
Half of these have more than 80k miles on them. That is how far people drive this car, not how long it lasts.
