2004 MG TF 1.8L Petrol · AW04 FDA

The vehicle passed its most recent MOT on 3 July 2026, but the overall maintenance trend is concerning due to chronic structural issues. While it has passed recently, there is a persistent pattern of corrosion related to the rear sub-frame that has appeared on almost every test since 2020. The 2023 failure was particularly severe, involving dangerous defects to the sub-frame attachment bracket and structural sill corrosion, suggesting that while repairs were made to pass the test, the underlying vulnerability to rust remains a significant ongoing risk for this chassis. With 73,223 recorded miles over 22 years, the vehicle has averaged approximately 3,328 miles per year, which is considerably low for its age. While low mileage generally implies less mechanical wear on the engine and gearbox, in the context of this model, it often suggests periods of standing. Low usage can lead to the degradation of rubber components, the seizing of brake calipers, and the accumulation of moisture in chassis cavities, which likely contributed to the recurring corrosion issues noted in the DVSA history. A prospective buyer must conduct a rigorous physical inspection of the rear sub-frame and sills. Given the history of dangerous corrosion and recurring advisories, you should use a torch and mirror to check for bubbling paint or flaking metal in the rear chassis areas and mounting points. During a test drive, listen for unusual knocks or clunks from the rear suspension, which could indicate compromised structural integrity. The current advisory regarding pitted and scored front brake discs suggests the vehicle may have been left stationary for extended periods; check for brake shudder under deceleration and inspect the disc surfaces for heavy oxidation or uneven wear. Beyond the structural concerns, the low annual mileage necessitates a check of all age-related perishables. Inspect the tyre sidewalls for fine cracking or perishing, as tyres often expire by age before they do by tread wear. Verify the service history for evidence of calendar-based fluid changes, as engine oil and coolant degrade over time regardless of mileage. Finally, check for evidence of the previously noted oil leaks and ensure the 12V battery is healthy, as infrequent use often leads to premature battery failure and charging system strain.
