Is the 2011 Insignia getting worse?

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

Test year	Pass rate
2023	71.5% +1.4 vs same-age
2024	70.6% +1.7 vs same-age

FAQs

Is a 2011 Vauxhall Insignia reliable?

2011-registered examples passed 70.7% of their MOT tests (65,919 tests, 2023–2025), +1.4 points versus all UK cars registered in the same year. At roughly 15 years old with a median 111,855 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2011 Insignia?

The median tested example shows 111,855 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.
