Buying a 2004 75? Two checks first

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.
