2014 Mercedes-Benz SLK 2.1L Diesel · SUE 601R

The 2014 Mercedes-Benz SLK presents a stable mechanical trajectory, culminating in a clean pass on 22 July 2025 at 60,922 miles with zero defects recorded. The maintenance trend remains consistent, showing no recurring structural or mechanical failures across the five-year history. A 2024 advisory flagged an offside front inner tyre wearing on the edge, indicating a minor consumable issue rather than an underlying defect, and the subsequent 2025 test confirms the problem was rectified. The vehicle has avoided the common pitfalls of corrosion, suspension degradation, or exhaust emissions failures that often afflict models of this age. Covering roughly 5,077 miles annually over twelve years, this SLK has seen exceptionally low usage. The mileage progression is steady rather than erratic, accumulating 1,761 miles between July 2024 and July 2025, and 2,087 miles between June 2023 and July 2024. Such light use typically preserves drivetrain components and braking systems, though prolonged periods of standing can cause latent issues like seized calipers or perished rubber bushes. The 2024 tyre wear advisory suggests the previous owner may have neglected routine alignment checks, as edge wear typically points to tracking issues rather than simple wear through mileage. Prospective buyers should conduct a thorough inspection of the suspension bushes and coil springs, as low-mileage vehicles often suffer from perished rubber rather than worn components. Pay close attention to the braking system; infrequent use can lead to binding calipers or uneven disc corrosion, even though the MOT records show no such faults. Verify the tracking and wheel alignment, given the historical offside front inner tyre wear flagged in 2024. A test drive over varied surfaces will reveal any latent suspension noise or brake drag that static inspections might miss. The structural integrity of the undercarriage warrants a close visual check for surface corrosion, particularly around the subframes and suspension mounting points, despite the clean MOT history.
