2004 Ford Mondeo 3.0L Petrol · AG04 MYM

Structural integrity and recurring component wear represent the primary mechanical concerns for this vehicle, particularly regarding progressive corrosion and suspension degradation. The most recent test on 24 November 2025 resulted in a pass, but it highlighted a worsening trend in chassis and suspension health, specifically noting corrosion on the rear subframe mounting prescribed area and corrosion on all three recorded coil springs (both rear and nearside front). This follows a history of multiple failures and advisories related to suspension components, including a fractured offside front coil spring in 2022 and repeated issues with wheel bearings and anti-roll bar linkages. The vehicle has covered 139,063 miles over its 22-year lifespan, which equates to an average annual usage of approximately 6,321 miles. This relatively low annual mileage is consistent with a vehicle that has seen light to moderate use, but the MOT history shows that even with lower mileage, the vehicle is subject to age-related deterioration. The presence of persistent oil leaks, noted in almost every test since 2021, and the recurring issues with tyres and exhaust emissions suggest that while the vehicle is not driven extensively, the mechanical components are reaching the end of their service life due to time and environmental exposure. A prospective buyer should pay close attention to the chassis and underside during a physical inspection, as the advisory regarding rear subframe mounting corrosion and the corroded coil springs indicates a risk of structural or suspension failure. On a test drive, listen for any metallic knocking or clunking sounds when driving over uneven surfaces or speed bumps, which could indicate that the corroded coil springs or the previously flagged anti-roll bar linkage ball joint are failing. Additionally, check for any wandering or pulling to one side, which may be linked to the steering rack gaiter issues noted in earlier years or the ongoing wear on suspension components. The persistent advisory for an oil leak, present since at least 2021, warrants a close inspection of the engine bay and undercarriage to determine the source and whether the leak is increasing. While the 2025 record describes the leak as not excessive, the long-term presence of this issue suggests a slow, ongoing seepage. Furthermore, given the history of wheel bearing play and tyre wear, the buyer should feel for any humming or grinding noises from the wheels at speed and check for any vibration through the steering wheel or brake pedal, which could indicate issues with the wheel bearings or braking system.
