2013 Mercedes-Benz SLK 2.1L Diesel · SP13 KXW

The vehicle is currently roadworthy, though the maintenance record shows a worsening trend regarding brake component condition. The most recent test in February 2026 at 62,594 miles flagged rear brake discs as worn, pitted, or scored. This follows a similar advisory from February 2025 at 59,999 miles where both front and rear discs were noted for surface degradation. While the vehicle passed these tests, the recurring appearance of surface corrosion suggests the car sits for extended periods or operates in damp environments. At 13 years old, the recorded mileage of 62,594 miles represents an average of approximately 4,815 miles per year. This low usage pattern explains the pitting observed on the brake rotors, as infrequent braking often fails to clear surface rust from the metal discs. The data shows consistent usage between 2022 and 2026, with no unexplained spikes in mileage accumulation. However, the 2024 test at 55,405 miles was partially compromised because a full-length shield on the underside prevented a comprehensive inspection of the lower chassis and structural components. A buyer must prioritize inspecting the braking system in person to determine if the pitting is merely superficial or if the discs have reached their minimum thickness. Given the low annual mileage, the calipers should be checked for seized pistons or perished seals, which frequently occur during inactivity. Because the 2024 inspection was obstructed, a thorough visual check of the underbody is essential to rule out structural corrosion or fluid leaks that the tester could not access. All rubber components and suspension bushes should be examined for cracking, as low mileage does not prevent age-related degradation of materials.
