Is the 2011 Alto getting worse?

Pass rate of 2011-registered cars across recent test years:

Test year	Pass rate
2023	75.3% +5.2 vs same-age
2024	74.3% +5.4 vs same-age
2025	73.0% +4.6 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 2011 Suzuki Alto reliable?

2011-registered examples passed 74.3% of their MOT tests (13,241 tests, 2023–2025), +5.1 points versus all UK cars registered in the same year. At roughly 15 years old with a median 64,110 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2011 Alto?

The median tested example shows 64,110 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.
