2015 Mercedes-Benz SL 3.0L Petrol · 3 BHM

The vehicle remains roadworthy, though the most recent inspection indicates the first signs of mechanical wear after years of clean records. In the March 2026 test at 28,689 miles, the tester flagged front brake discs as worn and pitted, alongside a non-excessive oil leak. While the car passed, these marks represent a shift from previous years and suggest the vehicle is beginning to show age-related degradation despite its low mileage. The mileage profile is exceptionally low for a 2015 model, averaging approximately 2,600 miles per year. Data from the 2022 test at 14,487 miles through the 2025 test at 26,411 miles shows a consistent, low-usage pattern. This low frequency of use generally reduces stress on the drivetrain and suspension components. However, long periods of standing often lead to the degradation of rubber seals and corrosion on exposed metal surfaces, which may be contributing to the pitting recently observed on the brake hardware. A buyer should focus their physical inspection on the reported oil leak noted in March 2026 to determine if it is a simple seal failure or a more significant engine issue. Given the low mileage, it is vital to check the condition of the hoses and suspension bushings, as these components can perish from age rather than use. The pitted front brake discs will require replacement to ensure optimal braking performance, and the underside should be checked for any surface rust that often accumulates on luxury vehicles that sit stationary for extended periods.
