2003 Mercedes-Benz CLK 2.6L Petrol · HT52 ACY

The vehicle is currently roadworthy but the maintenance history reveals a worsening trend regarding structural and suspension components. While it passed its latest test on 14 January 2026 at 55,481 miles, this followed a failure just one day prior. The tester flagged significant corrosion on the rear sub-frame which, although not yet classified as seriously weakened, represents a progressive issue. Additionally, the rear arm bush deteriorated progressed from worn in 2025 to excessively worn by 2026. The mileage profile is exceptionally low for a 23-year-old Mercedes, with 55,481 miles representing an average of approximately 2,412 miles per year. The data shows consistent annual testing with roughly 2,160 miles covered between January 2024 and January 2025, and another 1,301 miles between 2025 and early 2026. This low usage often leads to the degradation of rubber components and the oxidation of metal surfaces due to time and lack of movement rather than mechanical wear. A buyer must conduct a thorough inspection of the rear sub-frame to assess the depth of the corrosion noted in the January 2026 test. The recurring reports of worn suspension arm bushes across multiple years suggest that the front suspension geometry is reaching the end of its life and may require replacement to ensure proper handling. The front brake discs were noted as pitted and scored in early 2025, which is common on low-mileage vehicles that sit for extended periods. Furthermore, the persistent oil leak from the rear differential recorded in 2025 should be monitored to ensure it does not escalate into a significant failure.
