Is the 2017 S-Max getting worse?

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

Test year	Pass rate
2023	84.1% -1.7 vs same-age
2024	83.1% -0.8 vs same-age
2025	82.5% +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.

FAQs

Is a 2017 Ford S-Max reliable?

2017-registered examples passed 83.2% of their MOT tests (15,666 tests, 2023–2025), -0.8 points versus all UK cars registered in the same year. At roughly 9 years old with a median 61,882 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2017 S-Max?

The median tested example shows 61,882 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.
