2021 Mercedes-Benz B 1.9L Diesel · GF71 EEX

Repeated structural tyre failures dominate the documented roadworthiness record of this Mercedes-Benz, which successfully secured a clean pass on 2026-09-04 following an earlier test three months prior. This recent pass comes on the heels of a troubling historical pattern involving severe structural tire degradation. Specifically, the vehicle accumulated a Dangerous failure in June 2026 for an exposed ply on the nearside rear tyre, alongside a Major failure for a deep cut on the offside rear tyre. Furthermore, a June 2024 test yielded Major failures for sidewall cuts reaching the cords on both the nearside front and nearside rear tyres. This recurring vulnerability in rubber integrity points toward persistent exposure to sharp impacts, aggressive kerbing, or severe road surface hazards rather than isolated incidents, establishing a critical area requiring close physical inspection. An odometer reading of 42,200 miles across its five-year lifespan yields an average annual accumulation of roughly 8,440 miles, placing usage right in line with typical national driving patterns. This consistent accumulation indicates a steady operating rhythm rather than extended periods of static storage or punishing high-mileage fleet duties. Mechanically, this mileage level means the vehicle is operating in a transitional phase where factory-fitted suspension bushes, steering joints, and braking friction materials begin approaching standard wear thresholds, though the absence of corrosion or linkage advisories in the MOT data suggests the underbody hardware has not yet suffered accelerated deterioration from severe environmental exposure. When inspecting the vehicle prior to purchase, a thorough physical examination of the tyre sidewalls and tread blocks is mandatory, looking specifically for pinch lumps, uneven shoulder wear, or repaired cuts that might indicate a chronic alignment or suspension geometry issue. During the pre-purchase test drive, pay close attention to the steering feel and suspension feedback over rough tarmac or speed humps, listening carefully for any dull knocks or metallic clunks from the front and rear axles that would signify worn control arm bushes or failing damper mounts. Confirm that the steering tracks straight without pulling under braking and check that the brake pedal responds firmly without excessive travel or judder, ensuring the braking system performs reliably despite the historical focus on tyre-related structural failures.
