The 2012 Mercedes-Benz GL passes its MOT at 85.6%, which is a solid 5.6 percentage points above the UK average—but nearly three in ten have recorded dangerous defects at some point, which is a material concern for a buyer and suggests closer pre-purchase inspection is warranted. The diesel-dominated cohort (107 of 118 vehicles) maintains that 85.4% pass rate consistently, so fuel type isn't a differentiator here.

At 76,500 miles median, these eight-year-old vehicles are running fairly low mileage, yet they're averaging 1.75 failures per test and 11.9 advisories, indicating that wear and minor issues are already accumulating despite relatively gentle use. Before committing, have a pre-purchase inspection focus on suspension and brake components, where the advisory count suggests recurring wear.
