1987 Mercedes SL 3.0L Petrol · E684 CPD

The vehicle is currently roadworthy following a clean pass in September 2025 at 156,965 miles. However, the maintenance trend shows a period of mechanical instability that was only recently resolved. A failure just four days prior to the September 2025 test revealed a binding nearside rear service brake, a perished offside front ball joint dust cover, and excessive carbon monoxide emissions. While these issues were rectified to achieve the subsequent pass, the frequency of mechanical faults suggests a reactive approach to repairs rather than a preventative maintenance schedule. At 156,965 miles, this 39-year-old Mercedes has averaged approximately 4,025 miles per year over its lifetime. The data indicates extremely low usage between tests, for example, only 222 miles were recorded between August 2024 and September 2025. Such low mileage often implies the vehicle sits for long periods, which frequently correlates with the degradation of rubber components and the onset of fluid leaks. The consistency of low mileage over the last four years confirms the car is not driven regularly, increasing the risk of age-related wear rather than driven wear. A buyer must conduct a thorough physical inspection of the suspension and exhaust systems. The history highlights recurring issues with corrosion on the front coil springs in 2024 and a worn sub-frame pin or bush in 2023, indicating that structural and rubber components are deteriorating on this chassis. The persistent minor exhaust leak noted in both 2023 and 2024 suggests the exhaust system may be nearing a more significant failure. Given the recent binding brake noted in 2025, the brake calipers should be checked for seized pistons or internal corrosion to ensure the fault has not returned.
