2020 Mercedes-Benz GLB 220 AMG Line Prem D 4M A 1.9L Diesel · WN70 FEV

As a seasoned automotive inspector, I have evaluated the official DVSA MOT history for this 2020 Mercedes-Benz GLB 220, which successfully passed its most recent test on August 11, 2026, with zero recorded defects. Reviewing the historical test data reveals an exceptionally clean record, having also passed cleanly in 2025, 2024, and 2023 without a single failure or advisory item flagged by examiners. This maintenance and inspection trend is remarkably stable and reflects positively on the previous owners, demonstrating that the vehicle has been consistently presented for testing in a compliant, roadworthy condition without lingering structural or mechanical neglect. The vehicle is approximately six years old and shows a total recorded mileage of 51,646 miles, which translates to an entirely typical annual usage rate of roughly 8,600 miles per year. This balanced mileage profile indicates steady, regular use rather than erratic long-distance fleet pounding or prolonged periods of inactivity, meaning that high-stress drivetrain and suspension components have experienced normal wear consistent with the vehicle age. Because there are no unexplained gaps or extreme mileage spikes in the history, the mechanical systems have benefited from continuous operation, which generally prevents the premature drying of seals and the severe battery degradation often seen in underutilised vehicles. Despite the pristine MOT history, a prospective buyer must still conduct thorough physical checks during a pre-purchase inspection to ensure hidden wear items are addressed. Given the six-year age of the vehicle and its high-torque diesel four-wheel-drive system, you should meticulously inspect the condition of the brake discs and pads for scoring or lip formation, listen closely for any clunks or knocks from the multi-link suspension and anti-roll bar bushes during a test drive over uneven road surfaces, and check the inner shoulders of the expensive tyres for uneven wear indicative of subframe or wheel alignment drift. Additionally, you should verify that the service book is fully stamped to confirm that critical time-and-mileage-based maintenance, such as brake fluid changes and automatic transmission fluid servicing, has not been neglected despite the clean MOT passes. Inspect the engine bay for any signs of diesel weep around the common-rail injectors or turbocharger plumbing, test all electrical functions including the dual-screen MBUX infotainment and 4MATIC drivetrain engagement, and ensure the 12-volt battery holds a strong charge under load, as modern Mercedes-Benz vehicles place a heavy electrical demand on their auxiliary and primary power sources.
