By age
Pass rate by year first used
Older cars fail more often, so compare a car with others of its year. Cars up to 25 years old; years with fewer than 250 tests are left out.
| First used | Tests | Passed first time | Dangerous defect |
|---|---|---|---|
| 2008 | 462 | 89.0% | 1.5% |
| 2007 | 626 | 88.5% | 0.8% |
| 2006 | 579 | 86.9% | 2.4% |
| 2005 | 986 | 89.8% | 1.5% |
| 2004 | 252 | 89.3% | 1.2% |
Mileage
DB9 mileage by age
The median reading at the test: half the cars of that age had covered more, half less. Estimated from 1,000-mile bands, for cars up to 25 years old.
A car well above or below the typical figure is not a problem in itself, but the readings should rise steadily from one MOT to the next. A fall, or a long gap, is worth asking about.

| 17 years | 41,500 miles | 546 |
