2005 Ford Mondeo 1.8L Petrol · SO05 JSZ

The vehicle currently holds a valid MOT, but the maintenance trend indicates a concerning decline in structural integrity. While the car passed the November 2025 test at 90,286 miles, it followed a significant failure just two days prior at 83,813 miles. That failure revealed critical issues, including excessive corrosion on the offside rear outer suspension mounting which significantly reduced the structural strength of the sill. Although the immediate faults were addressed to pass, the presence of recurring exhaust leaks, corroded fuel pipes, and de-rating sub-frame corrosion suggests the vehicle is entering a stage where oxidation is beginning to outpace routine mechanical repairs. The mileage profile is notably low for a 21-year-old vehicle, having covered only 90,286 miles. This represents an average of approximately 4,300 miles per year. However, the data shows a recent surge in usage, with the car covering 8,482 miles between December 2023 and November 2025. This increased activity following long periods of low mileage may have accelerated the manifestation of issues, as stationary time often leads to the degradation of rubber components, brake seals, and fluid lines. A physical inspection must prioritize a thorough check of the underbody for structural rust. The history shows a persistent pattern of sub-frame corrosion since 2023, which escalated to a serious structural weakness in late 2023. The buyer should specifically examine the offside rear sill and the areas identified in the 2025 failure to ensure the repairs were effective rather than cosmetic. Furthermore, the anti-roll bar drop-links were flagged for play in the most recent test, indicating that suspension components are reaching the end of their functional life. Given the previous brake caliper leaks and exhaust leaks, an inspection of the exhaust system and fuel lines for further thinning or weeping is also essential to prevent future MOT failures.
