2014 Mercedes-Benz SLK 2.1L Diesel · LM14 XAC

The vehicle is currently roadworthy, but the maintenance history indicates a recent decline in mechanical oversight following a period of clean records. While the car passed its 2022 and 2023 tests without defects, the June 2025 inspections revealed a significant cluster of accumulated wear. Although the vehicle passed the re-test on 18 June 2025 after failing the previous day, the presence of a fractured coil spring and deteriorated suspension components suggests a reactive rather than proactive approach to servicing the chassis. At 12 years old with 66,777 miles, the SLK reflects low average annual mileage, averaging approximately 5,500 miles per year. This low usage typically suggests less strain on the engine and drivetrain, but it often correlates with degradation of rubber-based components. The gap of 4,763 miles recorded between June 2024 and June 2025 is consistent with this pattern, yet the sudden appearance of multiple faults in 2025 indicates that the vehicle may have sat stationary for extended periods or suffered from neglected service items despite the low odometer reading. A buyer must conduct a close inspection of the front suspension geometry, as the 2025 record flagged worn arm pin bushes on both sides and a severely deteriorated anti-roll bar linkage. The fractured nearside rear coil spring is a critical failure that necessitates a thorough check of the opposite side for similar stress fractures. Furthermore, the rear brake discs are visibly pitted and scored, which is a common issue on low-mileage vehicles where moisture causes surface corrosion due to lack of frequent braking cycles. The persistent central front oil leak was noted in at least 2024 and remains in 2025. While the tester classified this as not excessive, its recurring nature requires professional investigation to determine if the source is a weeping seal or a gasket. Given that the front tyres were at the legal limit and worn on the edge, the buyer should verify that these have since been replaced and that the alignment is correct to prevent immediate premature wear on new rubber.
