The 2006 Mercedes-Benz GL passes its MOT at 81.1%, just slightly above the UK average of 80%, which is respectable for a vehicle of this age—but the real concern is that one in three examples (33%) have recorded a dangerous defect at some point, a figure well above acceptable thresholds for a family SUV. The diesel variant, which makes up the vast majority of the cohort, performs marginally better at 81.4%, so fuel type isn't a differentiator here.
These GLs are running at a reasonable 88,500 miles median for their age, yet they're averaging 2.62 failures and a notably high 16.6 advisories per test, suggesting widespread wear issues across components like brakes, suspension, and lighting. Before buying, have a pre-purchase inspection focus on the cooling system and gearbox (common problem areas on this generation), and factor in that maintenance costs will likely be above average given the advisory count.
