2005 Mercedes-Benz SLK 1.8L Petrol · CW55 SLK

The 2005 Mercedes-Benz SLK presents as roadworthy with a stable maintenance trend, evidenced by the most recent test on 30 September 2025 at 91,761 miles which returned a pass with no defects recorded. Prior annual tests in January 2024 at 88,787 miles and January 2023 at 88,213 miles also passed cleanly. The vehicle shows no worsening mechanical faults across the available history. Recorded mileage sits at 91,761 against an age of roughly 21 years, equating to about 4,370 miles per year and marking low use for a 2005 convertible. The gap between the February 2022 failure at 85,935 miles and the February 2023 pass at 88,213 miles shows only 2,278 miles covered in that period. A five-day gap separates the 3 February 2022 failure from the 8 February 2022 pass at 85,946 miles, suggesting a quick rectification with no defects listed on either certificate. The clean record from 2022 onward implies the prior owner addressed the issue promptly and maintained the car to a reasonable standard thereafter. A buyer should still commission an in-person inspection of structural integrity and corrosion on the underside, sills, and suspension mounting points given the vehicle's age and likely periods of standing. Although no advisories appear for brake discs, coil springs, or suspension bushes, rubber components such as wishbone bushes and droplinks degrade with time regardless of low mileage. Verify the actual reason for the February 2022 failure through DVSA failure detail, as the summary shows no defects recorded on the certificate. Check for fluid leaks, tyre sidewall cracking, and brake caliper seizing during a pre-purchase examination, since these are not captured by a pass with no defects but remain common on a low-mileage 21-year-old SLK.
