Is the 2017 Arona getting worse?

Pass rate of 2017-registered cars across recent test years:

Test year	Pass rate
2023	73.4% -12.4 vs same-age
2024	74.4% -9.5 vs same-age
2025	74.0% -8.3 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 2017 SEAT Arona reliable?

What mileage is too high for a 2017 Arona?

The median tested example shows 42,654 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
