2007 Mercedes CL 500 5.5L Petrol · LD07 ONN

The latest MOT test on 2026-05-25 at 50,791 miles shows the vehicle passed, but the maintenance trend is currently worsening. A minor exhaust leak and oil misting from the offside rear shock absorber have appeared since the completely clean test in April 2025. Both rear tyres were flagged as worn close to the legal limit and wearing on the edges, indicating the vehicle may have been standing or the suspension geometry requires inspection. While the car remains roadworthy, these new defects suggest a lapse in recent upkeep or prolonged stationary periods. The recorded mileage of 50,791 miles over 19 years equates to roughly 2,673 miles annually, which is exceptionally low. The MOT records show a gradual accumulation from 45,718 miles in March 2022 to 50,791 miles in May 2026, averaging around 1,268 miles per year over this specific four-year window. Such light usage often points to extended periods of inactivity, which aligns with the recent appearance of corroded brake pipes, pitted discs, and edge-wearing tyres typical of a vehicle that sits stationary rather than being driven regularly. A recurring pattern of front suspension wear persists across multiple tests. Testers flagged worn front lower suspension arm pins and bushes in March 2022 and May 2024, alongside a slight play in the offside front ball joint in May 2024. Despite passing, the corrosion on the front upper suspension mounting brackets and suspension pipes noted in May 2024 raises concerns about long-term structural integrity. Brake discs have been consistently flagged as worn, pitted, or scored at both front and rear axles since March 2022, pointing to a lack of regular braking force or prolonged standing causing surface corrosion. A prospective buyer must thoroughly inspect the undercarriage and suspension components. Check the front suspension arm bushes and ball joints for excessive play, paying close attention to the corroded mounting brackets and pipes. Examine the brake discs for deep pitting and scoring that goes beyond typical consumable wear, and assess the rear brake pipe for active corrosion beneath any grease coating. The offside rear shock absorber requires close scrutiny for the source of the oil misting, as a failing unit will compromise handling and ride quality. Finally, verify the condition of the exhaust system to pinpoint the minor gas leak and assess whether the edge wear on the rear tyres stems from deferred wheel alignment.
