2021 MG ZS Exclusive EV Electricity · ST70 NLC

The most recent MOT test conducted on 10 March 2026 resulted in a pass with no recorded defects, indicating that the vehicle is currently compliant with minimum safety standards. However, an analysis of the preceding history reveals a period of neglected maintenance in mid-2025, when the vehicle failed due to dangerous tyre tread depths and received several advisories regarding the braking system. While the recent clean pass suggests that the immediate safety concerns and worn consumables were rectified, the recurring advisories for pitted and scored brake discs dating back to 2024 suggest a pattern of running components close to their wear limits. With 67,699 miles recorded over approximately five years, this vehicle has averaged roughly 13,540 miles per year, which is significantly higher than the UK average for this age bracket. This high-usage profile implies that the vehicle has been used regularly for commuting or long-distance travel, which is generally beneficial for maintaining electric vehicle battery chemistry through consistent cycling. However, this mileage also places greater stress on the mechanical chassis components, suspension, and braking systems. You should anticipate that wear-and-tear items such as tyres, brake pads, and suspension bushes will require more frequent inspection and replacement than a lower-mileage vehicle. During your test drive, you must pay close attention to the braking system to ensure the previous issues with discs and pads have been fully resolved. Listen for any metallic grinding or squealing sounds when braking, and feel for any vibration or shudder through the brake pedal or steering wheel, which would indicate warped or unevenly worn discs. Given the previous failure for low tyre tread, inspect the current tyres for even wear across the tread surface; uneven wear may indicate underlying issues with wheel alignment or worn suspension components like wishbones or dampers. Check the tyre sidewalls for any signs of perishing or bulging, as the high mileage suggests the rubber may be approaching the end of its functional life. Finally, ensure that the service history is documented and consistent with the high annual mileage. While electric vehicles have fewer traditional engine components, you should verify that the 12V battery health is stable and that the brake fluid has been changed according to the manufacturer's intervals to prevent moisture-induced corrosion in the calipers. Inspect the vehicle's underside for any signs of fluid leaks from the cooling system or excessive corrosion on the suspension mounting points, as the heavy usage pattern can accelerate the degradation of these critical structural and mechanical elements.
