2021 Mercedes-Benz EQC 400 AMG Line Premium 4M Electric · LG71 NOU

The most recent DVSA MOT test for this 2021 Mercedes-Benz EQC 400 was conducted on 11 August 2025 and resulted in a clean pass with no defects or advisories recorded. This represents a stable and satisfactory outcome at the time of testing, indicating that the vehicle met all statutory roadworthiness requirements on the day of inspection. The only notable items in the recorded MOT history are advisories from the previous test on 3 September 2024, where the offside front and offside rear tyres were flagged as worn close to the legal limit and worn on the edge. The absence of any further advisories in the latest test suggests these tyres were subsequently replaced, and no new wear-related issues have emerged. Overall, the trend between the two recorded tests is stable to improving, with no repeat defects, no structural advisories, and no recurring mechanical concerns. The recorded mileage of 29,351 miles over approximately five years equates to an annual average of around 5,870 miles, which is notably low for a vehicle of this age. This usage pattern is typical of a second car, a commuter with predominantly short urban journeys, or a vehicle that has experienced extended periods of standing between uses. Such low mileage has its own set of mechanical implications distinct from high-mileage wear. The drivetrain, suspension, and braking components are unlikely to have suffered significant frictional wear, but the vehicle may be more susceptible to issues arising from inactivity, including brake disc corrosion from moisture exposure without regular use to keep the surfaces clean, and potential degradation of rubber and fluid components that deteriorate with calendar age rather than mileage. Given the low annual mileage and the clean MOT history, a prospective buyer should focus inspection efforts on age-related and standing-related deterioration rather than high-mileage wear items. Begin with a thorough visual inspection of all four tyres, paying particular attention not only to tread depth but to sidewall condition, looking for cracking, perishing, or UV-related degradation, as low-mileage tyres can harden and develop age-related faults before the tread is exhausted. Examine the brake discs for any signs of corrosion pitting or surface rust, and during the test drive listen carefully for any brake shudder, vibration through the steering wheel, or squeal that might indicate warped discs from prolonged standing or a binding caliper that has seized due to infrequent use. Test the brakes progressively from higher speeds to confirm the pedal feels firm and the vehicle stops squarely without pulling to either side. Additionally, verify the 12V auxiliary battery health, as low-use vehicles are particularly prone to premature battery failure, and confirm whether the vehicle has been connected to a trickle charger or has required recent battery replacement. Check the condition and age of all vehicle fluids, including brake fluid, which has a typical service life of two years due to its hygroscopic nature, as well as the coolant and any transmission or drivetrain fluids that require time-based replacement regardless of mileage. Inspect the underside and suspension components for any signs of corrosion, particularly given that EVs can suffer from underfloor battery damage if corrosion is advanced. Finally, confirm the service book history to ensure that time-based servicing such as brake fluid changes, cabin filter replacement, and any manufacturer-specified inspections at fixed intervals have been carried out, as a low-mileage vehicle that has missed calendar-based services can present as much of a concern as a high-mileage example with neglected mechanical wear.
