2023 Mercedes-Benz EQB 300 AMG Line 4MATIC Electricity · LM73 NKC

A spotless MOT record to date indicates the EQB 300 AMG Line has presented no measurable safety or emissions concerns throughout its testing history, with the most recent assessment on 22 September 2026 confirming a clean pass and no recorded defects. This uninterrupted pass‑rate suggests the vehicle has consistently met the statutory requirements for roadworthiness, with no emerging trends of recurring advisories or failures to note. At three years old and 28 704 miles, the average annual accumulation sits around 9 500 miles, which aligns closely with typical usage patterns for a premium electric SUV. The mileage progression appears steady, with no abrupt spikes that would imply periods of intensive short‑term use. Such a moderate rate of wear generally translates to predictable consumption of consumables—tyre tread, brake pads, and suspension components—while placing the high‑voltage battery within the normal degradation envelope expected for a vehicle of this age and mileage. Although the MOT history reveals no specific faults, a prospective buyer should still verify the condition of the high‑voltage system and associated hardware. Inspect the charging inlet for signs of corrosion or loose connections, and confirm that the vehicle accepts a full charge without error messages. During a test drive, listen for any unusual whine or hum from the electric motor at low and high speeds, and watch for a consistent display of range that matches the vehicle’s reported state of charge. Check that the regenerative braking engages smoothly without abrupt pedal feel or unexpected deceleration, and ensure the conventional braking system delivers firm, even pedal pressure without pulsation. Finally, examine the conventional suspension and steering components for any clunking over bumps, uneven tyre wear, or a pull to one side, as these are not captured by the MOT but can affect ride quality and safety. Verify that all exterior lighting, windscreen wipers, and visibility aids operate correctly, and confirm that the onboard diagnostics do not flag any fault codes related to emissions, battery management, or safety systems. A thorough visual inspection of the underbody for corrosion, particularly around the high‑voltage cables and mounting brackets, will round out the pre‑purchase evaluation.
