2019 MG ZS 1.5L Petrol · LS11 JLS

The most recent MOT on 31 March 2026 was a pass, but it carried three advisories: the rear brake disc shows wear, pitting or scoring; the rear tyre and the nearside front tyre exhibit early signs of cracking or perishing. The previous year’s test also recorded front‑tyre tread at the legal limit on both sides, while the 2023 test noted noisy front wipers and the 2022 test was clean. Overall the pattern is one of a vehicle that has been kept road‑worthy but is now beginning to show age‑related wear on consumables, rather than any deteriorating safety‑critical faults. At 42 642 mi the MG ZS has logged roughly 6 100 mi per annum over its seven‑year life, which sits comfortably within the UK average of 7‑10 000 mi per year. The mileage does not suggest either prolonged periods of storage or unusually high usage; it is consistent with moderate, everyday driving. Consequently the wear observed on the tyres and rear disc is more likely a function of calendar ageing and normal road load rather than excessive mileage, although the relatively low annual distance does mean that components such as rubber and brake material may have aged more than they would have under higher‑kilometre use. Prospective buyers should give particular attention to the rear brake disc, which is already pitted. On a test drive listen for any low‑frequency squeal or feel for reduced braking efficiency, especially when applying the rear brake. Measuring disc thickness with a micrometer will confirm whether it is approaching the minimum safe limit (usually around 1.5 mm for this model). The tyres flagged for cracking or perishing should be examined for dry rot, sidewall bulges, or loss of tread depth; any hardening of the rubber or visible cracks warrants immediate replacement, as aged tyres can fail abruptly even if the tread appears adequate. The front‑tyre wear close to the legal limit recorded a year earlier suggests the need to check wheel alignment and suspension geometry – uneven wear often points to worn camber or toe settings, worn ball joints, or deteriorated front‑end bushes. A quick visual inspection of the front suspension bushes for cracking, oil seepage, or excessive play, combined with a test‑drive check for clunking over bumps, will highlight any impending suspension work. Given the vehicle’s age, a thorough calendar‑based inspection is advisable regardless of mileage. Verify the condition of the 12‑volt battery – a load test or checking voltage after a short idle can reveal diminished capacity that is common after several years of intermittent use. Inspect all fluid levels and consider a full service of engine oil, coolant, brake fluid and power‑steering fluid, as these can degrade over time even when the car is not driven heavily. Examine the under‑carriage and wheel arches for rust or corrosion, particularly around the rear brake disc mounting points and suspension mounting brackets, and ensure that the exhaust system is free of cracks or excessive rust. Finally, confirm that the service book is up to date with regular oil changes, timing‑belt or chain service (if applicable), and that any previous advisories have been addressed, as a well‑documented maintenance history will give confidence that the MG ZS remains mechanically sound for continued ownership.
