FAQs
Is a 2018 Ford Mondeo reliable?
2018-registered examples passed 87.4% of their MOT tests (21,084 tests, 2023–2025), +1.0 points versus all UK cars registered in the same year. At roughly 8 years old with a median 65,894 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2018 Mondeo?
The median tested example shows 65,894 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 2018 Mondeo?
In this cohort petrols pass 89.8% of tests against 86.8% 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.
