2004 MG ZS 2.5L Petrol · SJ54 AGS

The 2004 MG ZS has maintained a clean MOT history since its most recent test on 2025-05-07 , passing without any defects at 88,838 miles . This suggests the vehicle has avoided major mechanical or structural failures during its most recent annual cycle. The absence of advisories or repeated faults indicates no recurring issues with suspension bushes, coil springs, binding calipers, or corrosion-related failures—components commonly problematic in this model age. However, the 2024-04-30 record is anomalous, showing a failed test followed immediately by a pass at the same mileage, which may imply a retest or administrative oversight rather than genuine mechanical improvement. Without further context, this does not indicate a worsening trend, but buyers should verify whether the vehicle was genuinely retested or if the original failure was overlooked. The recorded mileage of 88,838 miles over 22 years equates to approximately 4,038 miles per year , a figure significantly lower than the UK average for a vehicle of this age. The most recent mileage jump occurred between 2023-04-24 (86,516 miles) and 2024-04-30 (87,999 miles) , a modest increase of 1,483 miles in a year, followed by another 939 miles by the next test. This suggests the car has spent extended periods stationary, which could accelerate wear on tyres, suspension seals, and battery health. The lack of rapid mileage accumulation also means consumables like brakes, clutch (if manual), and wiper blades may have been less frequently replaced than in high-mileage examples. Given the clean MOT record, the most critical in-person inspections should focus on tyre condition and tread depth , particularly if the vehicle has been stored for prolonged periods—failing twice on tread suggests basic upkeep may have been neglected. Examine the suspension bushes and coil springs for dry rot or excessive play, as these are common failure points in older MG models. The rear brakes , if drum-based, should be checked for binding or uneven wear, though the MOT history does not indicate prior issues. Structural integrity, especially around the floor pans and wheel arches , warrants scrutiny for corrosion, as this model is prone to rust progression over time. The exhaust system should also be inspected for leaks or sagging supports, as emissions-related failures are not reflected in the MOT history. Finally, verify the battery health and fluid levels , as low mileage can lead to degraded components.
