2005 Mercedes-Benz CLS 3.0L Diesel · MP55 AVV

The 2005 Mercedes-Benz CLS has maintained a consistent MOT pass record with no defects recorded across all five tests, most recently passing on 16 June 2025 at 145,245 miles. This suggests the vehicle has undergone regular, compliant servicing and has not encountered any recurring or critical failures during official inspections. The absence of advisories or major fault codes implies the core systems—braking, suspension, exhaust emissions, and structural integrity—have been adequately maintained. However, the most recent test occurred just over a year ago, which is within the standard 12-month MOT validity period, but buyers should note that the vehicle has not been subject to a test in the intervening period. This gap means there is no recent confirmation of its current condition beyond the last pass. The mileage progression indicates a steady usage pattern, averaging approximately 6,900 miles per year over the past five years. There are no abrupt jumps or prolonged periods of inactivity that might suggest neglect or extended storage. The interval between the 2020 and 2021 tests—just over a year—aligns with typical MOT cycles, though the subsequent tests in 2022 and 2024 were slightly delayed by a few months. This minor irregularity does not raise immediate concern, but it does mean the vehicle has not been through a test in the last year, leaving some uncertainty about wear on high-mileage components like suspension bushes, coil springs, or brake calipers. Given the lack of recorded defects, a buyer should prioritise an independent inspection of the suspension system, particularly the rear bushes and coil springs, which are prone to degradation at this mileage. The brakes, while not flagged in MOTs, should be checked for uneven wear or binding calipers, especially if the vehicle has experienced rapid acceleration or heavy loads. Corrosion around wheel arches, subframes, and exhaust mounts is another critical area to assess, as this model is susceptible to rust in high-moisture environments. The engine bay should also be examined for fluid leaks, as oil, coolant, or brake fluid contamination often indicates neglected servicing. While the MOT history is clean, these components are not routinely tested and may require attention beyond the last pass.
