2004 Rover 75 MOT pass rate: 61.2% (6,331 tests)
Is the 2004 75 getting worse?
Pass rate of 2004-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 60.7% -3.2 vs same-age |
|
| 2024 | 60.4% -3.7 vs same-age |
|
| 2025 | 62.9% -2.4 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 2004 Rover 75 reliable?
2004-registered examples passed 61.2% of their MOT tests (6,331 tests, 2023–2025), -3.1 points versus all UK cars registered in the same year. At roughly 22 years old with a median 102,884 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2004 75?
The median tested example shows 102,884 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 2004 75?
In this cohort petrols pass 67.2% of tests against 58.7% 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.
