2020 Mercedes-Benz E 3.0L Petrol · LM20 RCF

The most recent DVSA MOT test on this 2020 Mercedes-Benz E-Class was conducted on 3 July 2025 and resulted in a pass, with no defects or advisories recorded against the vehicle. It is worth noting that this pass followed directly on from a failure recorded the day prior, on 2 July 2025, although no defect details are listed against that failure entry in the available history. Subsequent advisory or rectification information is not documented, so the precise nature of the issue that caused the initial failure cannot be determined from the official record alone. Across the four MOT entries available, the broader pattern shows clean passes in 2023, 2024, and again in 2025, with the single failure sandwiched between the earlier clean results, suggesting that whatever prompted the 2025 failure was addressed promptly and has not reappeared on the most recent test. From a maintenance trend perspective, the overall picture is therefore one of stability, with the caveat that the buyer should satisfy themselves as to what rectification work was carried out between 2 July and 3 July 2025. Turning to the recorded mileage of 25,694 miles over an approximate six-year period, this equates to an annual usage rate of around 4,282 miles, which is considerably below the average mileage for a vehicle of this age. While low annual mileage reduces wear on major drivetrain and consumable components such as clutch, brake friction material, and engine internals, it introduces its own set of mechanical considerations. Vehicles that have spent extended periods standing are particularly susceptible to corrosion of brake discs, leading to surface pitting or rust scoring that can manifest as brake shudder or vibration under heavy pedal application. Brake calipers, especially slider pins and guide surfaces, can also seize from infrequent use, causing uneven pad wear and pulling under braking. Rubber components throughout the vehicle, including suspension bushes, engine and gearbox mounts, coolant hoses, and drive belts, are prone to perishing and hardening when not exercised regularly, and tyres may develop sidewall cracking even if tread depth remains adequate. Given the clean advisory record but the low usage profile, prospective buyers should place particular emphasis on a thorough physical inspection rather than relying solely on the MOT history. The tyres should be examined closely for age-related sidewall cracking, perishing, or uneven wear patterns, and the production date code on the sidewall verified, as tyres older than five or six years may require replacement regardless of remaining tread. The 12V battery should be tested for state of charge and cranking performance, as low-use vehicles are particularly vulnerable to premature battery failure, and if the vehicle is fitted with the common Mercedes auxiliary battery, this should also be checked. Brake discs should be inspected for any lipping, corrosion, or uneven surface, and the calipers exercised to confirm smooth operation without binding. Fluid services should be verified, as brake fluid is hygroscopic and degrades over time regardless of mileage, typically requiring replacement every two years, while coolant, transmission fluid, and the oil service history should be confirmed against the manufacturer's recommended schedule rather than against mileage alone. A careful service book stamp check, combined with any digital service records from Mercedes-Benz, will be essential to confirm that time-based maintenance has been carried out. On a test drive, the buyer should listen carefully for any clonks or knocks from the suspension over uneven surfaces, which may indicate perished bushes or worn coil springs common to low-mileage vehicles, and pay particular attention to brake pedal feel for any sponginess suggesting fluid degradation or any juddering under braking pointing to disc corrosion. The steering should feel precise and free from any vagueness or knocking, and the automatic transmission should provide smooth, timely gear changes without hesitation or flare, as low usage can lead to mechatronic or valve body issues developing gradually. Engine cold start behaviour should be observed, and the vehicle allowed to reach operating temperature while monitoring for any warning lights, irregular idling, or unusual exhaust emissions, particularly given that diesel and petrol E-Class variants of this era are subject to strict emissions testing. Finally, confirming the gap between the 2025 failure and pass, ideally through a service invoice or workshop record, will provide complete confidence in the vehicle's current roadworthiness.
