2020 MG ZS 1.5L Petrol · CK20 GKG

The defining mechanical characteristic of this MG ZS is a persistent theme of tyre wear combined with emerging wear items on the braking and suspension systems, rather than any outright test failure. Across the four recorded MOT tests spanning 2023 to 2026, the vehicle has passed every inspection cleanly, with no failures recorded, but the advisory pattern is worth attention. The most recent test on 9 June 2026 was recorded as a pass with no defects, which on the surface suggests a stable trend, yet the three preceding tests each carried advisories. The 2025 test flagged a nearside rear tyre worn close to the legal limit on the edge, pitted rear brake discs, and corrosion on the offside front coil spring, while the 2024 test recorded a nail in an offside rear tyre and both front tyres worn close to the limit on the inner edge. This combination of recurring inner-edge tyre wear and suspension corrosion is the most consistent mechanical theme in the file, and a buyer should treat it as the primary area of scrutiny. In terms of usage, the recorded mileage of 43,526 against an approximate six-year age equates to around 7,254 miles per year, which is broadly typical for a small family SUV of this type and does not suggest either prolonged standing or unusually heavy use. There are no conspicuous gaps in annual mileage progression that would indicate long periods off the road, and the vehicle has been subjected to continuous MOT testing, implying regular road use. At this accumulation rate, wear on consumables such as brake pads, tyres and exhaust components is expected to be moderate rather than severe, though the advisory history already shows the discs and tyres accumulating wear at a pace that suggests replacement will be due in the near term rather than the distant future. For the suspension, the recorded corrosion on the offside front coil spring in 2025 is the most specific item to investigate, particularly as coil spring corrosion on the MG ZS has been a known issue that can progress to fracturing if left unattended. On a test drive, listen carefully for any metallic knocking or clonking over uneven road surfaces, particularly at low speed over speed humps and potholes, and pay attention to whether the front end feels unsettled or transmits harsh impacts into the cabin. Inspect the visible coils of the springs in the wheel arches for any flaking paint, surface rust that has deepened into pitting, or any signs of cracking. The repeated inner-edge front tyre wear noted in 2024 also warrants a check of the front wheel alignment, as consistent inner-edge wear typically points to either excessive negative camber or a geometry issue following suspension component wear. Request a current alignment printout or have the geometry checked independently. On the braking system, the advisory on the rear brake discs in 2025 indicates surface pitting and scoring that had not yet reached a seriously weakened state, but this type of wear progresses and a buyer should expect rear discs and possibly pads to require replacement within the next service interval. On the test drive, feel for any vibration or judder through the brake pedal under firm application, listen for any grinding or scraping noises from the rear wheels, and check whether the car pulls to one side under braking, which could indicate a binding caliper. The tyres themselves should be inspected for uneven shoulder wear and checked for age, as the advisory pattern suggests they may already be close to replacement. Finally, a thorough inspection underneath the vehicle for any signs of corrosion on subframe, brake pipes, and suspension arms is advisable given the recorded spring corrosion, as corrosion issues on related components can develop concurrently on a vehicle of this age and provenance.
