2006 Mitsubishi Colt MOT pass rate: 61.8% (7,740 tests)
Is the 2006 Colt getting worse?
Pass rate of 2006-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 62.0% -2.2 vs same-age |
|
| 2024 | 62.2% -2.0 vs same-age |
|
| 2025 | 61.1% -3.9 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 2006 Mitsubishi Colt reliable?
2006-registered examples passed 61.8% of their MOT tests (7,740 tests, 2023–2025), -2.6 points versus all UK cars registered in the same year. At roughly 20 years old with a median 88,152 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2006 Colt?
The median tested example shows 88,152 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 2006 Colt?
In this cohort petrols pass 62.5% of tests against 55.0% 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.
