FAQs

Is a 2017 Peugeot 308 reliable?

2017-registered examples passed 79.6% of their MOT tests (27,265 tests, 2023–2025), -4.4 points versus all UK cars registered in the same year. At roughly 9 years old with a median 57,930 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2017 308?

The median tested example shows 57,930 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 308?

In this cohort petrols pass 81.5% of tests against 78.1% 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.
