2005 MG Tf MOT pass rate: 75.2% (3,654 tests)
Is the 2005 Tf getting worse?
Pass rate of 2005-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 74.8% +10.6 vs same-age |
|
| 2024 | 75.7% +11.5 vs same-age |
|
| 2025 | 75.3% +10.0 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 2005 MG Tf reliable?
2005-registered examples passed 75.2% of their MOT tests (3,654 tests, 2023–2025), +10.7 points versus all UK cars registered in the same year. At roughly 21 years old with a median 52,286 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2005 Tf?
The median tested example shows 52,286 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.
