2008 Mercedes C 1.8L Petrol · S111 ACP

This 2008 Mercedes C-Class presents a stable but watchful maintenance picture. The most recent MOT on 5 March 2026 at 94,836 miles passed, yet the tester again flagged a corroded rear sub-frame, noting it was not seriously weakened. This is a recurring advisory, first appearing in the April 2025 test at 92,617 miles, which also recorded general corrosion under the vehicle. The trend is not worsening into a failure, but the corrosion is persistent and demands close monitoring. A clean bill of health in April 2023 at 91,045 miles shows the corrosion developed relatively recently, likely accelerated by standing or damp storage. The mileage profile is notably low for an eighteen-year-old vehicle. Covering just 94,836 miles over roughly eighteen years equates to approximately 5,269 miles annually. The record shows a significant gap between August 2022 at 83,616 miles and April 2023 at 91,045 miles, where the car accumulated 7,429 miles in eight months after a period of lighter use. The subsequent years saw very modest increases, with only 753 miles covered between April 2023 and April 2024, and 819 miles between April 2024 and March 2026. This pattern suggests the vehicle has spent extended periods stationary, which often accelerates corrosion on sub-frames, brake lines, and seals despite low mileage. A buyer should prioritise a thorough under-vehicle inspection focused on structural integrity. The recurring rear sub-frame corrosion advisory, combined with the 2025 note of general under-body corrosion, warrants a close check for any perforation or weakened mounting points. The April 2024 test flagged slight corrosion to the ferrules on both front brake hoses, a detail that should be re-inspected given the car's tendency toward corrosion. Suspension components, particularly rear trailing arm bushes and coil springs, should be examined for perishing from age and standing. Brake discs and pads may show surface corrosion from limited use, and tyre condition should be verified, as the August 2022 test flagged both front tyres worn close to the legal limit.
