Buying a 2016 GLA? Two checks first

FAQs

Is a 2016 Mercedes-Benz GLA reliable?

2016-registered examples passed 83.0% of their MOT tests (31,346 tests, 2023–2025), +1.7 points versus all UK cars registered in the same year. At roughly 10 years old with a median 61,490 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2016 GLA?

The median tested example shows 61,490 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 2016 GLA?

In this cohort petrols pass 87.2% of tests against 82.4% 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.
