2014 Mercedes-Benz SLK 2.1L Diesel · VH10 CKY

The vehicle is currently roadworthy, but the maintenance history reveals a worsening trend regarding braking system components. While it passed the most recent test in November 2025 at 63,993 miles, this followed a failure just two days prior at 63,932 miles. The failure was due to rear brake discs being seriously weakened, a condition that was rectified before the immediate retest. This suggests a reactive maintenance approach where parts are only replaced once they fail inspection rather than through preventative scheduling. At 63,993 miles, the SLK shows low mileage for its twelve-year age, averaging approximately 5,300 miles per year. The data indicates a significant gap in usage, with only 1,496 miles covered between May 2024 and December 2024, and roughly 9,000 miles in the following eleven months. Such low-frequency use often leads to surface corrosion on brake rotors and seals when the vehicle sits stationary, which aligns with the reports of pitted and scored discs noted across multiple test years. A buyer must conduct a thorough physical inspection of the braking assembly and suspension. The record shows a persistent pattern of pitting and scoring on all four brake discs dating back to 2023, alongside uneven inner edge wear on the front tyres flagged in late 2025. This tyre wear typically indicates an alignment issue or worn suspension bushes that require professional attention to prevent premature tyre degradation. Additionally, check the calipers for signs of seized pistons, as the low-mileage usage pattern increases the likelihood of hydraulic components sticking due to inactivity.
