Moderate sample. 325 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.
The 2020 Mercedes-Benz GLB 200 AMG Line is a serious concern at MOT time: only 43.5% pass first time, nearly half the UK average of 80%, and nearly one in four vehicles have picked up a dangerous defect at some point. This is an unusually poor result for a relatively young, low-mileage car—the median is just 32,280 miles—and suggests systemic quality or design issues rather than owner neglect.
The average vehicle has accumulated 0.15 failures and 1.3 advisories, pointing to recurring minor problems that compound into test failures. Before buying one of these, insist on a full pre-purchase inspection by an independent Mercedes specialist and review the complete MOT history; the first-time pass rate suggests you're more likely than not to face repair bills soon after purchase.
The 2020 Mercedes Benz Glb 200 Amg Line Auto passes its MOT first time more often than most UK vehicles (92.4% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
These stats describe 325 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.
