2018 Mercedes-Benz C 2.1L Diesel · KP18 TXZ

The vehicle currently presents as roadworthy, but the maintenance history reveals a concerning pattern of reactive rather than proactive care. While it passed its latest test on 30 May 2024 at 51,790 miles, it failed just one mile prior due to multiple defects. The trend is unstable, as the owner appears to only address critical issues once a formal failure occurs, rather than performing routine preventative maintenance between annual inspections. At 51,790 miles over eight years, the car has averaged approximately 6,474 miles per year, which aligns with typical low-mileage usage for this age. The mileage data shows consistent intervals, with roughly 11,000 miles covered between May 2023 and May 2024, and approximately 6,600 miles between April 2022 and May 2023. This steady usage suggests the mechanical components are not under excessive stress, but the low mileage does not mask the recurring neglect of basic consumable items. A buyer must prioritise a thorough inspection of the tyres, as the records from May 2023 and 2024 show all four tyres consistently failing at or below the legal limit of 1.6mm. This indicates a total disregard for tyre tread depth. Furthermore, the 2024 failure for an inoperative Malfunction Indicator Light (MIL) is a significant red flag; it suggests the vehicle's self-diagnostic system was bypassed or faulty. A professional diagnostic scan is required to ensure no hidden engine faults or emissions issues remain present. The recurring note regarding engine covers and under trays preventing full inspection is a potential concern for identifying fluid leaks or structural corrosion on the lower chassis. The buyer should request that these trays be removed to check for oil or coolant leaks and rust that the tester could not have seen. Given the 2022 advisory for uneven tyre wear on the rear axle, a wheel alignment and inspection of the rear suspension bushes and arms should also be verified to prevent premature failure of future sets of tyres.
