2021 Mercedes-Benz GLB 200 AMG Line Prem D 4M A 1.9L Diesel · WM21 ASZ

This Mercedes-Benz GLB has demonstrated a stable roadworthiness record over the past two MOT cycles, both passing without defects in June 2024 and June 2025 at 33,445 and 45,196 miles respectively. The absence of advisories or failings across these tests suggests the vehicle has not experienced recurring mechanical or structural issues that would warrant immediate concern. However, the most recent test occurred just over a year ago, meaning the current roadworthiness status is not confirmed beyond that point. Given the typical lifespan of critical components like suspension bushes, brake calipers, and exhaust systems, a thorough inspection is essential to verify no wear has developed since the last pass. The recorded mileage of 45,196 miles over five years—approximately 9,000 miles annually—falls within the expected range for this vehicle’s age and model. There are no evident gaps or spikes in usage that would indicate neglect or excessive wear beyond standard expectations. The consistent mileage accumulation between tests (around 11,750 miles per year) aligns with moderate, regular use rather than sporadic or high-mileage operation. This pattern does not immediately raise red flags regarding consumable wear, though it does not guarantee the absence of deferred maintenance elsewhere. Given the clean MOT history, the primary focus of an in-person inspection should centre on components that commonly fail between tests, particularly those not directly assessed by the MOT. The suspension—including coil springs, bushes, and dampers—should be checked for uneven wear, fluid leaks, or excessive play, as these are not always captured in a standard MOT. Brake systems, while not failed in previous tests, warrant scrutiny for uneven pad thickness, binding calipers, or corrosion on discs, especially if the vehicle has been exposed to moisture. The exhaust system should be inspected for rust penetration or loose mounts, as these can develop silently between MOTs. Finally, the underbody and wheel arches should be examined for corrosion, particularly around the subframe and wheel bearings, given the GLB’s exposure to road salt and potential for hidden deterioration.
