FAQs

Is a 2017 SEAT Leon reliable?

2017-registered examples passed 84.4% of their MOT tests (53,728 tests, 2023–2025), +0.4 points versus all UK cars registered in the same year. At roughly 9 years old with a median 59,108 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2017 Leon?

The median tested example shows 59,108 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.
