Is the 2006 DB9 getting worse?
Pass rate of 2006-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|

|
| 2024 | 90.8% +26.6 vs same-age |
|
| 2025 | 88.4% +23.4 vs same-age |
The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

What mileage is too high for a 2006 DB9?
