Is the 2015 Swift getting worse?

Pass rate of 2015-registered cars across recent test years:

Test year	Pass rate
2023	86.9% +6.3 vs same-age
2024	84.7% +6.1 vs same-age
2025	83.6% +6.6 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 2015 Suzuki Swift reliable?

2015-registered examples passed 85.1% of their MOT tests (36,714 tests, 2023–2025), +6.3 points versus all UK cars registered in the same year. At roughly 11 years old with a median 54,686 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2015 Swift?

The median tested example shows 54,686 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.
