2004 Nissan 350 Z 3.5L Petrol · BF04 XYX

Structural corrosion and recurring suspension degradation define the mechanical history of this vehicle, which most recently passed its MOT on 18 February 2026 following a failure for a dangerous tyre defect. While the vehicle has successfully navigated testing, the persistent flagging of corrosion on the rear vehicle structure and torque bars indicates a deteriorating condition in the undercarriage that requires professional assessment. The transition from clean test records in 2018 and 2019 to a pattern of structural and component-based advisories suggests that the vehicle is now entering a phase where age-related fatigue is becoming a consistent factor in its roadworthiness. Accumulating 107,867 miles over 22 years results in an average of approximately 4,903 miles per annum, a figure that sits well below the national average for a vehicle of this type. This low-intensity usage profile often masks the impact of environmental exposure, as evidenced by the repeated reports of corrosion on coil springs and structural members. The mechanical risk here is not necessarily high-mileage wear on internal engine components, but rather the degradation of rubber bushes, seals, and metal fasteners that suffer when a vehicle remains stationary for extended periods or is used only intermittently in damp conditions. Prospective buyers must prioritise a thorough inspection of the rear subframe and torque bars, as the 2026 advisories point to significant oxidation that could compromise the integrity of the rear suspension geometry. During a test drive, listen specifically for metallic clunking or knocking noises from the rear over uneven surfaces, which would indicate that the corroded torque bars or the previously noted coil springs are failing to dampen road shocks effectively. Any sensation of the rear end feeling unsettled or wandering during cornering should be treated as a direct consequence of the structural concerns noted by testers. The front end of the vehicle warrants equal scrutiny, particularly given the historical reports of tyre inner-shoulder wear and anti-roll bar linkage play. If the steering feels imprecise or if there is a noticeable vibration through the wheel at motorway speeds, this may be linked to the previously recorded distorted road wheel or worn suspension linkages. Verify that the exhaust system, which required repair in 2021, remains free of leaks; listen for a blowing sound or increased cabin resonance under load, which would suggest that the joint corrosion noted in earlier tests has progressed or that the exhaust hangers have failed. Given the history of tyre-related failures and advisories, ensure all four tyres are checked for even tread depth and that the steering geometry is professionally aligned to prevent rapid, uneven wear.
