Is the 2014 Insignia getting worse?

Pass rate of 2014-registered cars across recent test years:

Test year	Pass rate
2023	70.5% -6.9 vs same-age
2024	70.8% -4.8 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 2014 Vauxhall Insignia reliable?

2014-registered examples passed 70.5% of their MOT tests (74,523 tests, 2023–2025), -5.4 points versus all UK cars registered in the same year. At roughly 12 years old with a median 104,236 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2014 Insignia?

The median tested example shows 104,236 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 2014 Insignia?

In this cohort petrols pass 74.8% of tests against 70.1% 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.
