2020 MG ZS 1.5L Petrol · CK20 GJO

Corrosion on all four coil springs and recurring braking issues represent the primary mechanical concerns for this vehicle, following a failure on 27 May 2026. While the car passed its most recent test on 28 May 2026, the record shows a deteriorating trend regarding the braking system and suspension components. The transition from a clean 2024 record to multiple major failures in May 2026, specifically involving parking brake efficiency and a severely grabbing offside rear secondary brake, indicates recent significant wear or component degradation. The presence of advisories for all four coil springs being corroded suggests that the structural integrity of the suspension springs is currently under scrutiny. The recorded mileage of 40,215 miles over approximately six years equates to an average annual usage of roughly 6,702 miles. This usage pattern is consistent with typical light-to-moderate driving, which generally implies less cumulative wear on drivetrain components and engine internals compared to high-mileage vehicles. However, the specific defects noted in the MOT history, such as pitted brake discs and corroded springs, may be more closely related to environmental factors or the frequency of use rather than high mileage alone. A prospective buyer should pay close attention to the braking performance during a test drive to address the history of binding and grabbing issues. Listen for any unusual noises from the wheels when braking and feel for any unevenness or judder in the brake pedal, which could indicate the pitted or scored discs mentioned in previous advisories. The advisory regarding a nearside front service brake binding, even if not currently excessive, warrants a check for any pulling to one side during deceleration or a noticeable heat build-up from that wheel after a period of driving. Regarding the suspension, the widespread advisory for corrosion on all four coil springs necessitates a physical inspection of the spring coils for heavy surface rust or signs of fracturing. During the test drive, pay close attention to the vehicle's response to road imperfections; any knocking, clunking, or metallic banging sounds when traversing bumps could indicate that the corroded springs or associated suspension bushes are failing. Given the recent failure of the parking brake, it is also advisable to ensure the handbrake engages firmly and holds the vehicle securely on an incline without excessive travel.
