Is the 2016 GLC getting worse?

Pass rate of 2016-registered cars across recent test years:

Test year	Pass rate
2023	87.5% +4.3 vs same-age
2024	85.9% +4.7 vs same-age
2025	85.0% +5.5 vs same-age

The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

FAQs

Is a 2016 Mercedes-Benz GLC reliable?

2016-registered examples passed 86.2% of their MOT tests (27,306 tests, 2023–2025), +4.8 points versus all UK cars registered in the same year. At roughly 10 years old with a median 68,274 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2016 GLC?

The median tested example shows 68,274 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.
