Which year to buy? →
The 2015 Mercedes-Benz GL passes its MOT at 87.8%, well above the UK average of 80%, which is genuinely impressive—but nearly 35% have recorded dangerous defects at some point, a significant red flag that warrants a full pre-purchase inspection by a specialist. The diesel-heavy cohort (608 of 702 vehicles) maintains that strong 87.6% pass rate, suggesting the engine platform is fundamentally sound.
These cars are running at a sensible 59,737 miles on average, so you're not looking at heavily thrashed examples, yet they still average 1.14 failures and 6.8 advisories per test. Before you buy, insist on a Mercedes-trained technician's inspection focusing on suspension, braking, and electrical systems—the advisory count hints at the complexity of ownership, and that high dangerous-defect percentage means preventative diligence will save you money and safety grief.
The 2015 Mercedes Benz Gl has a decent first-time pass rate (87.8%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.
These stats describe 702 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
