2003 MG Tf MOT pass rate: 71.8% (7,906 tests)
Is the 2003 Tf getting worse?
Pass rate of 2003-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 72.7% +8.3 vs same-age |
|
| 2024 | 71.3% +6.5 vs same-age |
|
| 2025 | 71.4% +5.2 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 2003 MG Tf reliable?
2003-registered examples passed 71.8% of their MOT tests (7,906 tests, 2023–2025), +6.7 points versus all UK cars registered in the same year. At roughly 23 years old with a median 60,004 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2003 Tf?
The median tested example shows 60,004 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.
