FAQs

Is a 2021 Mercedes-Benz GLE reliable?

2021-registered examples passed 89.3% of their MOT tests (6,841 tests, 2023–2025), -1.1 points versus all UK cars registered in the same year. At roughly 5 years old with a median 34,842 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2021 GLE?

The median tested example shows 34,842 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.
