1998 Ferrari 550 Maranello 5.5L Petrol · S707 AJL

The most recent MOT test completed on 25 September 2025 resulted in a pass with no recorded defects. Evaluating the overall maintenance trend, the vehicle demonstrates a stable and improving profile. While there was a significant failure in April 2021 regarding an exhaust Lambda reading outside specified limits, the subsequent clean passes suggest that the exhaust emissions system and related sensor components have been effectively addressed. An earlier advisory regarding a park light in 2020 also appears to have been resolved, indicating that the vehicle is being maintained to a standard consistent with its high-value status. The recorded mileage of 35,206 miles over 28 years represents an extremely low annual usage rate of approximately 1,257 miles per year. From a mechanical standpoint, this indicates minimal wear on the internal engine components, gearbox, and drivetrain. However, such low usage often implies that the vehicle has spent considerable periods stationary. For a high-performance vehicle of this vintage, long-term standing can be as detrimental as high mileage, potentially leading to the degradation of rubber components, the settling of fluids, and the onset of corrosion in areas not frequently subjected to airflow or movement. Given the vehicle's low-mileage and age-related profile, a prospective buyer must look beyond simple wear indicators. It is essential to inspect the tyres for sidewall cracking or perishing, as age-related rubber degradation can compromise safety even if tread depth remains high. Check the brake discs for heavy corrosion or pitting and test for binding calipers, which often occurs when seals become stiff from inactivity. During the test drive, pay close attention to the suspension for any clunks or knocks that might indicate perished bushes or worn coil springs, and listen for any irregularities in the exhaust note that could hint at a recurrence of the previous Lambda sensor issues. Furthermore, the buyer should verify that time-based maintenance has been strictly followed rather than relying solely on mileage-based intervals. This includes checking for recent changes to engine oil, coolant, and brake fluid, as these fluids degrade chemically over time. Inspect the engine bay thoroughly for signs of weeping from gaskets or seals that may have shrunk due to lack of use. Finally, ensure the 12V battery and charging system are in good health and that all electrical components, including all exterior lighting, are fully functional to avoid the minor electrical advisories seen in the past.
