2021 Mercedes-Benz 200 1.9L Diesel · NV21 TTF

Tyre health dominates the mechanical narrative of this 2021 Mercedes‑Benz 200, with recurring rear‑tyre concerns culminating in a dangerous failure on the near‑side rear wheel in February 2026. While the latest MOT on 25 February 2026 recorded a clean pass, the same period revealed a major defect on the near‑side rear tyre – a cut deep enough to expose the ply and cords – and multiple advisories about the off‑side rear tyre approaching the legal tread limit. The pattern of rear‑tyre wear and damage, rather than any systemic fault, defines the vehicle’s current road‑worthiness profile. At 51 464 miles the car averages roughly 10 300 miles per year, a mileage rate that sits comfortably within normal UK usage for a five‑year‑old executive saloon. The MOT history shows regular annual testing with no prolonged gaps, indicating the vehicle has been kept on the road consistently rather than stored for extended periods. This steady accumulation suggests that consumable wear items such as tyres, brakes and suspension components would be expected to be at a moderate stage of life, aligning with the mileage‑related advisories observed. Prospective buyers should focus the pre‑purchase inspection on the rear tyre set. Examine the near‑side rear tyre for any visible cuts, bulges or exposed cords, and measure tread depth on both rear wheels to confirm they exceed the 1.6 mm legal minimum by a comfortable margin. On‑road, listen for thumping or vibration when the vehicle is under load or cornering, which can indicate uneven tyre wear or a compromised sidewall. Replace the rear tyres promptly if any of these symptoms are present, and consider a full tyre rotation and balance to even out wear across the set. The off‑side rear tyre’s advisory about approaching the legal limit also warrants replacement or at least a professional assessment before the next seasonal change. The remaining recorded defects are minor – a defective off‑side windscreen wiper blade and a full boot advisory – both of which are inexpensive remedial items. No failures were logged for brakes, lights, emissions or structural components, so the vehicle’s core mechanical systems appear sound from the MOT perspective. During a test drive, verify that steering is free of pull, that the brakes apply smoothly without judder, and that there is no unusual noise from the suspension. Addressing the tyre issues and the simple wiper replacement will bring the car back to a fully compliant and safe state for continued use.
