2009 Mercedes-Benz Clc MOT pass rate: 61.4% (9,730 tests)
Is the 2009 Clc getting worse?
Pass rate of 2009-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 60.7% -6.1 vs same-age |
|
| 2024 | 61.7% -4.4 vs same-age |
|
| 2025 | 61.9% -4.2 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 2009 Mercedes-Benz Clc reliable?
2009-registered examples passed 61.4% of their MOT tests (9,730 tests, 2023–2025), -5.0 points versus all UK cars registered in the same year. At roughly 17 years old with a median 99,685 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2009 Clc?
The median tested example shows 99,685 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 2009 Clc?
In this cohort petrols pass 64.1% of tests against 56.7% 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.
