Is the 2012 508 getting worse?

Pass rate of 2012-registered cars across recent test years:

Test year	Pass rate
2023	70.6% -1.7 vs same-age
2024	71.2% +0.2 vs same-age
2025	69.4% -0.9 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.

FAQs

Is a 2012 Peugeot 508 reliable?

What mileage is too high for a 2012 508?
