2008 Maserati Quattroporte 4.7L Petrol · JB05 AWB

This Maserati Quattroporte presents a concerning trend regarding structural and suspension integrity despite its exceptionally low mileage. While the car has averaged only 2,452 miles per year over its 18-year life, the recent MOT history suggests that the vehicle has suffered from significant corrosion and component wear that typically correlates with long periods of standing or storage in damp conditions. The most critical observation is the emergence of corrosion issues on the rear subframe and anti-roll bar, which were flagged in 2025. While these were not deemed excessive at the time, the presence of structural corrosion on a vehicle of this age is a red flag that requires professional assessment. The fact that the car required a re-test in 2025 due to a failed track rod end indicates that the suspension components are beginning to degrade, likely due to age-related perishing of rubber bushings and seals rather than high-mileage wear. The recent 2026 MOT shows that the suspension issues are continuing, with slight play now noted in the offside front suspension arm ball joint. This indicates a pattern of recurring front-end wear that suggests the vehicle is currently in a phase of declining mechanical health. The low mileage is a double-edged sword; while the engine and drivetrain may have seen limited use, the suspension and chassis components are clearly showing the effects of age and potential inactivity. You should be cautious about the long-term impact of the subframe corrosion. Even if it was not considered excessive in 2025, corrosion on critical structural mounting points can worsen rapidly if the car is returned to regular use or exposed to road salt.
