2006 Mercedes-Benz S-Class 3.0L Diesel · A500 JBC

The vehicle remains roadworthy, having passed its most recent inspection in February 2026. The maintenance trend shows a stable but recurring pattern of attention required for the braking system. While the 2026 test at 67,711 miles flagged the front inner brake discs as being pitted and scored, this follows a similar issue noted in January 2022 where both front discs were reported as worn and corroded on their inner faces. The mileage profile is exceptionally low for a twenty-year-old vehicle, averaging approximately 3,386 miles per year. The data shows a consistent but sparse usage pattern, with a gap of 11,464 miles between February 2023 and February 2024, and another 8,969 miles between February 2024 and March 2025. This low mileage suggests minimal mechanical wear on the drivetrain, yet it often leads to accelerated corrosion on metalwork components due to the vehicle sitting for extended periods. A buyer must prioritise a thorough physical inspection of the braking system, as the 2023 test identified corroded rear brake pipes covered in grease, which often indicates an attempt to hide surface rust or previous leaks. The recurring reports of pitted front discs suggest that the calipers may be sticking or that the discs are suffering from atmospheric corrosion. Given the age and low usage, the rubber components in the suspension and bushings should be checked for cracking and dry rot, as age-related degradation often precedes mileage-based wear in vehicles of this era.
