Is the 2004 Previa getting worse?

Pass rate of 2004-registered cars across recent test years:

Test year	Pass rate
2023	65.6% +1.6 vs same-age
2024	62.4% -1.7 vs same-age
2025	65.2% -0.1 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.
