2021 Mercedes-Benz E 300 AMG LN NGT ED PRM + DE A 1.9L Electric diesel · LP21 HHN

This 2021 Mercedes-Benz E300 presents a stable and reassuring maintenance trend, with no defects recorded across all three MOT tests. The most recent test on 9 April 2026 at 70,823 miles returned a completely clean pass, indicating that the vehicle currently meets DVSA standards across all checked categories including brakes, suspension, steering, tyres, lights, and exhaust emissions. The absence of advisories or failures across the entire history suggests consistent upkeep rather than reactive repairs. The mileage accumulation pattern warrants closer scrutiny. Between 11 April 2025 at 52,035 miles and 9 April 2026 at 70,823 miles, the vehicle covered 18,788 miles in a single year. That is a significant jump from the prior annualised rate of roughly 3,500 miles between August 2024 and April 2025. Such a sharp increase could indicate a change in ownership or usage pattern, possibly transitioning from light local use to sustained motorway commuting. High annual mileage accelerates wear on consumables including brake discs and pads, tyres, suspension bushes, and damping components, even if the MOT record currently shows no faults. Despite the clean MOT history, the mileage profile justifies a thorough in-person inspection of structural and mechanical components. A buyer should examine the inner wheel arches, sills, and subframe mounting points for corrosion, particularly given the vehicle's age and the possibility of sustained high-speed use. Suspension arms, drop links, and anti-roll bar bushes should be checked for play or deterioration, as these components degrade faster under high-mileage conditions. Brake calipers should be inspected for signs of binding, and the condition of the exhaust system, including the diesel particulate filter, should be verified through a cold start and visual check. The clean MOT record is encouraging, but it does not substitute for a physical inspection by a qualified technician. High-mileage vehicles can present latent issues between annual tests, particularly around drivetrain mounts, turbocharger pipework, and electronic systems common to this model. A pre-purchase inspection covering these areas will provide the buyer with a more complete picture of the vehicle's long-term reliability.
