2009 Mercedes-Benz CLK 2.1L Diesel · MF09 LDD

This seventeen year old Mercedes CLK presents an immaculate official roadworthiness record, with four consecutive MOT passes and zero advisories or defects logged from the 2022 test through the most recent examination on 13 October 2025. A clean sheet across four annual tests on a vehicle of this age is exceptional, particularly given the corrosion-prone reputation of Mercedes products from this era. While the absence of advisories is encouraging, prospective buyers should interpret it with measured optimism rather than absolute confidence; MOT testing is a relatively narrow snapshot of safety-critical items at a single point in time, and components such as coil springs, suspension bushes, brake pipes, and subframe mounting points can deteriorate between annual examinations without crossing the failure threshold. The consistency of clean results over four years, however, does establish a credible baseline of mechanical integrity at the point of each test. The recorded mileage of 185,103 against a 2009 registration equates to an annual accumulation of roughly 10,888 miles, which is broadly typical for the vehicle's age and suggests steady, regular use rather than long periods of standing or extreme high-mileage wear. There are no anomalous gaps or sudden spikes in the recorded odometer readings, and the consistent year-on-year attendance at MOT indicates the car has remained in active service rather than being laid up for extended periods. For a CLK of this vintage, sustained regular use is mechanically favourable, as it keeps seals, gaskets, and drivetrain components lubricated and working, and reduces the risk of seized calipers, perished rubber, and the kind of dormant corrosion that afflicts stored vehicles. The mileage level does, however, place the engine, automatic transmission, and suspension components firmly in the realm of high-wear items, particularly given the additional stress that a heavier grand tourer coupé places on its underpinnings when compared to a smaller saloon. Given the pristine MOT record but the inherent age and mileage of the vehicle, a prospective buyer should focus their physical inspection on the components most likely to be approaching service intervals on a Mercedes of this generation. On a test drive, listen carefully for clonks or knocking from the front suspension over uneven surfaces, which would suggest worn lower control arm bushes, anti-roll bar drop links, or top mount bearings, none of which would necessarily trigger an MOT advisory until they became severely deteriorated. Check for any pulling to one side under braking or a soft, spongy pedal feel, as the brake servos, flexible hoses, and disc wear are common age-related concerns. Inspect the underside carefully for any oil misting from the engine and gearbox sump areas, and pay particular attention to the subframe mounting points and rear axle components for any bubbling paint or surface corrosion that may not yet have been severe enough to be flagged. A fluid change history for the automatic transmission should also be verified, as Mercedes units of this era benefit significantly from regular ATF and filter renewal beyond 100,000 miles. Finally, although the test history is faultless, the cosmetic and functional condition of the convertible roof mechanism, hydraulic cylinders, and associated seals warrants particular scrutiny on this CLK variant, as these are expensive items that fall outside the MOT scope but represent significant potential repair liabilities. Verify smooth operation of the roof through a full open and close cycle, observing whether it completes the sequence without hesitation, warning messages, or unusual mechanical noise. Equally, confirm that all dashboard warning systems illuminate correctly on ignition, as hidden electronic faults on a vehicle of this complexity can be costly to diagnose. With a clean MOT history, sensible mileage, and continuous use, this CLK represents a structurally promising basis for purchase, provided that the inevitable age-related service items on suspension, drivetrain seals, and roof hydraulics are confirmed in good order before commitment.
