FAQs
Is a 2017 Mazda Cx-3 reliable?
2017-registered examples passed 88.3% of their MOT tests (14,373 tests, 2023–2025), +4.3 points versus all UK cars registered in the same year. At roughly 9 years old with a median 44,168 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2017 Cx-3?
The median tested example shows 44,168 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 2017 Cx-3?
In this cohort petrols pass 88.8% of tests against 85.3% 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.
