2005 Mercedes-Benz CLK 3.0L Diesel · KS05 YZX

The 2005 Mercedes-Benz CLK presents a stable and reassuring roadworthiness profile based on the DVSA MOT record. The most recent test, conducted on 15 December 2021 at 172,457 miles, passed with zero defects recorded. A prior test on 13 December 2021 at 172,182 miles also shows no defects listed against the failure, suggesting the rectification was swift and effective. This pattern indicates a vehicle that has been maintained to a consistently high standard in recent years, with no recurring mechanical or structural faults flagged by the testing regime. The mileage accumulation tells a clear story of a car used steadily but not excessively. Between the November 2020 test at 151,266 miles and the December 2021 test at 172,457 miles, the vehicle covered approximately 21,191 miles in just over 12 months. This is a notable spike compared to the earlier interval, where the car added only 10,392 miles between November 2019 at 140,874 miles and November 2020 at 151,266 miles. The average annual mileage of roughly 8,212 miles over 21 years is typical for the age, but the sharp increase in late 2021 suggests a period of heavier use or long-distance driving. Critically, the mileage has not moved at all since December 2021, meaning the car has stood for nearly five years without a recorded MOT. This extended stationary period raises concerns about deterioration from lack of use rather than wear from use. A buyer should approach this CLK with caution focused on components that degrade when a vehicle sits idle rather than one that has been driven regularly. Tyres are a primary concern, as rubber perishes with age regardless of tread depth, and five years of static storage almost certainly means all four tyres and the spare require replacement regardless of their visual condition. Brake discs and calipers are also at risk of surface corrosion and seizure from prolonged inactivity, so a thorough inspection of braking performance on a road test is essential. The fuel system, including the tank, lines, and injectors, should be examined for contamination or varnish buildup from old petrol. Beyond the immediate concerns of long-term storage, the CLK's age and mileage warrant a close inspection of suspension bushes, coil springs, and shock absorbers, as these components fatigue over time regardless of use. The exhaust system and underbody should be checked for corrosion, particularly around mounting points and box sections. Given the clean MOT history, there is no evidence of recurring structural or mechanical neglect, but the five-year gap since the last test means the current condition can only be verified through a hands-on inspection and a fresh MOT before any purchase is completed.
