2009 MERCEDES-BENZ SL3.5L Petrol

The vehicle presents a strong roadworthiness profile with a stable and currently improving maintenance trend. Following a single failure in late February 2023 at 47,679 miles, the car has passed three consecutive tests with zero defects recorded. The most recent inspection conducted in September 2025 at 51,683 miles confirms that the vehicle remains in a clean condition, with no mechanical or structural failures flagged by the MOT tester. The mileage pattern is exceptionally low for a 17-year-old vehicle, averaging approximately 3,040 miles per year. The data shows periods of limited use, such as the 2,408-mile interval between March 2024 and September 2024, and the 2,408-mile gap over the final year of the recorded history. While this low mileage suggests minimal wear on the drivetrain and engine components, it also increases the risk that rubber components and fluid seals may degrade due to age and lack of use rather than mechanical de-and-tear. Despite the clean-sheet records, a physical inspection must focus on components prone to age-related failure. A buyer should specifically check the condition of the suspension bushes and coil springs, as low-mile vehicles often suffer from perished rubber over time. The braking system should be examined for seized calipers or corrosion, which frequently occur when a car sits for extended periods. Given the age of the SL, a thorough check of the chassis for structural integrity and rust is essential, as the MOT only inspect for surface corrosion until it reaches a point of structural weakness.
