2022 Mercedes-Benz GLB 200 AMG Line Auto 1.3L Petrol · T29 RRB

As a seasoned UK automotive inspector, I have evaluated the official DVSA MOT history and vehicle usage data for the 2022 Mercedes-Benz GLB 200 AMG Line Auto, which successfully passed its most recent test on the third of July 2026 at a recorded mileage of 51,062 miles with zero defects or advisories recorded. This clean result follows an identical fault-free pass on the twenty-ninth of July 2025, establishing an exemplary and stable maintenance trend for the vehicle across its formative years. The absence of historical advisories or failures indicates that previous owners have maintained the compact luxury SUV to a high standard, with no chronic structural or mechanical neglect evident from the test logs. The vehicle is approximately four years old as of September 2026 and has accumulated 51,062 miles, translating to an annual usage rate of roughly 12,766 miles per year. This mileage accumulation is notably higher than the typical UK national average for a petrol family SUV, indicating that the GLB has likely spent a significant portion of its life undertaking longer motorway journeys rather than short urban trips. While high mileage can accelerate wear on consumables such as brake discs, suspension damping, and drivetrain components, motorway-heavy running is mechanically preferable to stop-start city driving as it reduces thermal cycling stress on the engine and minimizes excessive clutch wear within the dual-clutch automatic transmission. Given the brisk mileage accumulation and modern technical complexity of this AMG Line model, your physical pre-purchase inspection should focus heavily on consumable health and verified service history. Even though the MOT tests have been completely clean, inspect the front brake discs and pads closely for a lip of wear and scoring, and listen carefully during the test drive for any suspension clunks or knocks over potholes, which would signal early wear in the MacPherson strut front or multi-link rear suspension bushes. Furthermore, check the inner shoulders of all four low-profile tyres for uneven wear patterns that could indicate poor wheel alignment or geometry strain resulting from high-speed motorway impacts. Inside the cabin and beneath the bonnet, verify that the digital service book is fully stamped in accordance with Mercedes-Benz manufacturer schedules, ensuring that crucial oil changes, spark plug replacements, and dual-clutch transmission fluid changes have not been deferred. Pay attention to the operation of the automatic transmission during a cold start, ensuring smooth engagement without hesitation or judder when shifting between drive and reverse. Check the electronic parking brake functionality and ensure all advanced driver assistance systems and infotainment features operate without error messages, confirming that the vehicle's electrical architecture remains robust despite its elevated mileage.
