In 2025, 30,380 Mercedes-Benz Gle cars had a regular MOT in Great Britain. 87% passed first time, compared with 81% for all cars of the same ages, which makes the Gle better than average. Adjusted for age, it ranks 47 of the 217 most-tested car models.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 3 years old, 88% of Gles passed first time (all cars that age: 88%). By 10 years, that figure is 89% (all cars: 72%). It beats the average car at every age with enough data, from 6 to 10 years.

What to check when buying a used Gle
Based on where the Gle fails more often than other cars, these are the checks worth making before you buy:
- Plates and VIN: Check the number plates are legal and the VIN matches the V5C logbook. More
- Tyres: Check tread across the whole width (uneven wear hints at alignment or suspension faults), and look for cuts, bulges and mismatched brands. Repair guide
- Visibility: Check the windscreen for chips in the driver’s view, the wipers for smearing and the washers for working jets. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
