Is the 2008 308 getting worse?

|---|---|---|

|
| 2024 | 57.5% -7.4 vs same-age |

FAQs
Is a 2008 Peugeot 308 reliable?
2008-registered examples passed 58.0% of their MOT tests (23,733 tests, 2023–2025), -7.1 points versus all UK cars registered in the same year. At roughly 18 years old with a median 100,337 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2008 308?
The median tested example shows 100,337 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 2008 308?
In this cohort petrols pass 60.4% of tests against 56.3% 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.
