2006 Mercedes-Benz SL 5.4L Petrol · CP55 AMG

The vehicle is currently roadworthy, though the maintenance trend shows a shift toward developing mechanical wear as it ages. The most recent test in May 2026 at 88,308 miles identified a non-excessive oil leak and a damaged windscreen, alongside misting on the offside front shock absorber. This progression follows a previously noted misting on the nearside front shock recorded in March 2022 at 72,144 miles, suggesting the suspension dampers are reaching the end of their service life. The mileage profile is notably low for a 20-year-old vehicle, averaging approximately 4,400 miles per year. There is evidence of significant fluctuations in usage, such as the gap between May 2017 and January 2019 where the car covered only 6,071 miles. While the low mileage suggests less strain on the drivetrain and engine, the intervals between tests indicate the car may have spent long periods stationary. This pattern of intermittent use often leads to the degradation of rubber-based components and seals, which is consistent with the issues found in the record. A physical inspection must focus heavily on the braking system and suspension geometry. The history shows a persistent struggle with parking brake efficiency, dating back to 2019 and culminating in a failure in early 2020 due to a structural tyre bulge and marginal performance. Furthermore, recurring reports of uneven tyre wear inner edges in 2011, 2013, and 2019 suggest chronic alignment issues or worn suspension bushes. The buyer should check the control arms and bushings for excessive play. The oil leak identified in the 2026 test requires close monitoring to determine if it is a minor seal or a more significant leak. Given the presence of under-trays mentioned in 2013 and 2019 which previously obscured the tester's view of brake pipes, an inspector should ensure that no hidden corrosion or damage exists beneath the bodywork. The body damage noted in May 2025 should also be scrutinized to ensure it has not compromised the structural integrity of the chassis.
