FAQs
Is a 2017 Vauxhall Insignia reliable?
2017-registered examples passed 80.8% of their MOT tests (46,061 tests, 2023–2025), -3.2 points versus all UK cars registered in the same year. At roughly 9 years old with a median 69,452 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2017 Insignia?
The median tested example shows 69,452 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 2017 Insignia?
In this cohort petrols pass 85.2% of tests against 79.6% 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.
