In 2025, 120,082 Peugeot 308 cars had a regular MOT in Great Britain. 63% passed first time, compared with 69% for all cars of the same ages, which makes the 308 worse than average. Adjusted for age, it ranks 197 of the 217 most-tested car models.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 4 years old, 83% of 308s passed first time (all cars that age: 87%). By 18 years, that figure is 46% (all cars: 57%). It trails the average car at most ages, most noticeably at 18 years (11 points behind).

What to check when buying a used 308
Based on where the 308 fails more often than other cars, these are the checks worth making before you buy:
- Steering: Feel for play or knocking through the wheel, and check power-steering fluid isn’t leaking. More
- Body and structure: Get underneath with a torch: sills, jacking points, subframe mounts and floor pans. Structural rust is the failure that can make a car uneconomic to fix. Repair guide
- Emissions and leaks: Look for oil and coolant leaks underneath, listen for exhaust blows on a cold start, and watch for smoke when revving. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
