Is the 2012 C30 getting worse?

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

Test year	Pass rate
2023	72.1% -0.3 vs same-age
2024	69.6% -1.4 vs same-age
2025	68.4% -1.9 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 Volvo C30 reliable?

2012-registered examples passed 70.0% of their MOT tests (8,615 tests, 2023–2025), -1.2 points versus all UK cars registered in the same year. At roughly 14 years old with a median 86,224 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2012 C30?

The median tested example shows 86,224 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.

Should I buy the petrol or diesel 2012 C30?

In this cohort petrols pass 73.4% of tests against 67.2% for diesels. Mileage and use can explain part of that gap, so treat it as a reason to inspect DPF and emissions history, not a fuel-type verdict.
