Is the 2017 Giulietta getting worse?

2023	85.3% -0.5 vs same-age
2024	85.1% +1.2 vs same-age

FAQs

Is a 2017 Alfa Romeo Giulietta reliable?

2017-registered examples passed 84.1% of their MOT tests (4,516 tests, 2023–2025), +0.0 points versus all UK cars registered in the same year. At roughly 9 years old with a median 51,070 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2017 Giulietta?

The median tested example shows 51,070 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 Giulietta?

In this cohort petrols pass 85.8% of tests against 81.4% 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.
