Is the 2018 Clio getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 83.3% -4.7 vs same-age |
|
| 2024 | 78.3% -8.0 vs same-age |
|
| 2025 | 72.9% -11.8 vs same-age |
The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

FAQs
Is a 2018 Renault Clio reliable?
2018-registered examples passed 78.2% of their MOT tests (58,367 tests, 2023–2025), -8.2 points versus all UK cars registered in the same year. At roughly 8 years old with a median 38,158 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2018 Clio?
The median tested example shows 38,158 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 2018 Clio?
In this cohort petrols pass 79.1% of tests against 74.3% 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.
