2021 Mercedes-Benz C 220 AMG Line NGT ED Prem D A 1.9L Diesel · LL21 AAM

The 2021 Mercedes-Benz C 220 AMG has demonstrated a stable roadworthiness profile over its five-year ownership period, with two consecutive successful MOT tests preceding the most recent pass on 2026-03-03. Between those assessments, a single advisory appeared on 2025-02-28 concerning nearside front tyres that were worn close to the legal limit and exhibited edge wear consistent with the 5.2.3 (e) category. This pattern reveals a vehicle that remains fundamentally roadworthy with intermittent attention required rather than systemic failure. The absence of subsequent fails following resolution of the tyre advisory suggests the underlying issue was isolated and managed effectively through routine maintenance before the next MOT. At 51,856 miles on a 2021 model, the vehicle accumulates approximately 10,371 miles annually, which aligns with expected usage patterns for a mid-range saloon over a five-year lifespan. The gap between the 2025-02-28 MOT and the 2026-03-03 MOT spans roughly eleven months, while the interval from the last pre-advisory MOT on 2024-02-22 to the 2025-02-28 test represents nearly a full year, indicating regular servicing intervals. The current mileage sits comfortably within the typical range for this age group, suggesting the car has not accumulated excessive wear prematurely. However, the progression from a clean MOT to an advisory and back to clean status does warrant verification that the tyre issue was fully resolved prior to the most recent test, as persistent under-inflation or continued uneven wear could affect handling and safety. The primary concern for a prospective buyer centers on the nearside front tyres that triggered the 5.2.3 (e) advisory in early 2025. During a test drive, the buyer should pay particular attention to whether the vehicle exhibits any lateral pull during cornering, as worn edge tyres often develop subtle alignment problems that manifest as steering bias. Over bumps, particularly on hard surfaces, listen for a rhythmic knocking or thudding noise that could indicate the tyres are wearing unevenly and may be losing contact with the road surface. Additionally, inspect the tyres visually for any exposed sidewall material, bulges, or significant tread separation around the outer shoulders, as these conditions can compromise grip and increase the likelihood of hydroplaning in wet weather. Confirming the correct tyre pressures and ensuring the tyres are properly rotated will help determine whether the advisory reflects genuine wear or simply a narrow margin of compliance. Beyond the tyre advisory, buyers should conduct a thorough visual inspection of the subframe and wheel arches, especially in areas prone to salt and moisture exposure, although no corrosion was specifically noted in the MOT records. Given the vehicle's age and mileage, it is prudent to verify that the suspension bushings have not developed noticeable play or creaking sounds during movement, as older components can degrade silently until a sudden loss of damping occurs. The brake system showed no issues in any recorded MOT, but a test drive should still confirm firm, responsive braking without pulsations through the pedals. Overall, the car presents a functional roadworthiness picture with one resolved advisory, but the tyre condition warrants confirmation that the nearside front tyres have returned to acceptable tread depths and even wear before committing to purchase.
