2023 Mercedes-Benz EQC 400 AMG Line Premium 4M Electric · RO23 ABU

The most recent MOT test on 19 March 2026 confirmed this EQC 400 AMG Line Premium in a passable roadworthy condition at 49,620 miles, with no defects or advisories recorded. This represents a stable maintenance trend, as the vehicle has not failed or required major remedial work in the available MOT history. The absence of recurring faults suggests that, at least in terms of statutory inspection criteria, the car has been kept within legal limits for emissions, brakes, suspension, and structural integrity since the last test. However, the lack of a pre-March 2026 MOT record means there is no historical context for how the vehicle performed before this period, leaving potential earlier issues unaccounted for. The recorded mileage of 49,620 miles over approximately three years—assuming the vehicle was first registered in late 2023—implies an unusually high annual average of around 16,540 miles. This exceeds typical usage patterns for a luxury electric vehicle of this age, which often see significantly lower mileage. While high mileage alone does not definitively indicate neglect, it does suggest accelerated wear on high-stress components such as suspension bushes, coil springs, brake calipers, and drivetrain seals. The absence of a pre-2026 MOT also means there is no data to confirm whether earlier owners adhered to recommended service intervals, particularly for electric-specific systems like battery health or high-voltage wiring integrity. Given the sparse MOT history, a prospective buyer should prioritise an independent inspection of critical wear items that are not routinely checked under MOT standards. Focus on the suspension—particularly the condition of rear coil springs and mounting bushes, which are prone to fatigue at higher mileages—and verify there is no excessive play or binding in the steering or rear-wheel drive units. The brake system warrants scrutiny, especially the rear calipers and discs, as binding or uneven wear can develop without triggering an MOT failure. Additionally, inspect the underbody for corrosion around the wheel arches and sills, as this is a common failure point for EVs exposed to salted roads. Given the lack of service records, a battery health check—including voltage levels and thermal management system functionality—would be advisable, as lithium-ion degradation can accelerate with high mileage. Finally, confirm the integrity of the high-voltage wiring harness and connectors, as these are not covered by MOT but are critical for safe operation.
