2009 Mercedes SLK 5.4L Petrol · AV08 HRV

The vehicle remains roadworthy, but the most recent inspection indicates a shift from a clean record to developing faults. While the car passed four consecutive tests without defects between 2021 and 2024, the October 2025 test at 70,363 miles flagged corrosion on the nearside rear, offside rear, and offside front brake pipes. The specific note regarding these pipes being covered in grease or other material suggests a potential attempt to mask surface rust or a previous fluid leak that requires immediate attention. The mileage profile is remarkably low for a 17-year-old vehicle, averaging approximately 4,139 miles per year. Between October 2021 and October 2025, the car covered 5,933 miles, representing less than 1,500 miles annually annually. This low usage often correlates with less wear on the engine and drivetrain, but it frequently accelerates the degradation of rubber-based components and promotes atmospheric corrosion on metal surfaces, which is consistent with a vehicle that sits for long periods or is only used for short local trips. A buyer must conduct a thorough physical inspection of the braking system to ensure the corrosion on the brake pipes has not compromised the structural integrity of the lines. The presence of grease on these pipes is a red flag that necessitates a check for weeping seals or poor repairs intended to hide fluid loss. Given the age and low mileage, the inspection should also focus on the suspension bushes, rubber seals, and tyre cracking, as these components perish over time regardless of the number of miles driven.
