2013 Mercedes-Benz C 2.1L Diesel · SL63 PGY

The vehicle is currently roadworthy, though the maintenance trend reveals a recurring issue with tyre condition and alignment. The latest test in February 2026 at 58,557 miles resulted in a pass despite an advisory for a dig in the sidewall of the nearside front tyre. This follows a failure in February 2025 at the same mileage due to a structural cut in the offside rear tyre reaching the cords. While the immediate safety failures were rectified, the persistence of tyre damage suggests a reactive rather than proactive maintenance approach. The mileage profile is notably low for a thirteen-year-old vehicle, averaging approximately 4,500 miles per year. There is a significant gap of 3,949 miles between the January 2024 and February 2025 tests, followed by 1,278 miles covered in the year leading up to the 2026 test. This low annual usage often reduces wear on drivetrain and engine components, but it increases the risk of rubber-based components perishing, brake seizing, and fluid degradation if the car sits stationary for extended periods. A buyer must scrutinise the front suspension geometry, as the 2023 test at 49,753 miles flagged the nearside front tyre for wearing on both inner and outer edges. This uneven wear, combined with repeated sidewall damage, indicates potentially worn bushes or incorrect tracking settings that require adjustment. Physical inspection should also focus on brake discs for corrosion and caliper movement, as low-mileage Mercedes frequently suffer from surface rust and seized pistons when not used frequently enough to clear the components.
