2005 Mercedes-Benz SLK 2.0L Petrol · T428 AJB

The most recent DVSA examination on 17 October 2025 returned a pass, which on the surface suggests the vehicle is currently roadworthy; however, just two days earlier on 15 October 2025 the car failed on multiple lighting and wiper related majors, meaning the pass was achieved only after remedial work was carried out at short notice. Reviewing the full sequence of tests reveals a maintenance trend that is broadly stable but punctuated by recurring and increasingly serious advisories, particularly around suspension components, sub-frame corrosion, tyre perishing, and exhaust mountings. The 2024 failure was particularly concerning, with a Dangerous defect recorded for a nearside front lower suspension arm pin or bush likely to become detached, alongside Major failures for a worn ball joint, excessively corroded suspension mounting area, and seriously weakened rear sub-frames on both sides. That this vehicle was returned to the road and has since passed suggests repairs were undertaken, but the rapid recurrence of similar corrosion-related advisories on the 2025 test indicates that the underlying structural deterioration has not been fully resolved and is likely to progress further. The recorded mileage history is unfortunately insufficient to draw firm conclusions about annual usage, and there is not enough data to compare mileage against the vehicle's age of over twenty years. Given that this is a 2005 Mercedes-Benz SLK now approaching its twenty-first year, any current odometer reading should be cross-checked against the vehicle's age, service book stamps, and any available V5C or maintenance invoices. An older SLK showing very low mileage may have spent extended periods standing, which on a convertible brings its own set of mechanical concerns including seized brake calipers, perished rubber components, and degraded fluids. Conversely, if the car has been used regularly, the 2025 advisory items relating to tyre cracking and sub-frame corrosion suggest it has been exposed to the typical British combination of winter road salt and wet weather that accelerates structural decay. Given the recurring advisories across multiple test cycles, a prospective buyer should carry out a focused physical inspection beginning with the suspension and underbody. The nearside front suspension arm, mounting point, and associated bushes were the subject of Dangerous and Major defects in 2024, so the buyer should listen for any clonking or knocking noises over speed bumps and uneven surfaces, and check for uneven front tyre wear which would indicate worn bushes or a loose ball joint. The rear sub-frame corrosion flagged in both 2024 and 2025 should be inspected closely on a ramp or over a pit, paying particular attention to the mounting points and any welded repairs, as corrosion in these areas can progress rapidly once initiated. The nearside front steering rack inner joint play noted in 2023 should be rechecked for any worsening clonks or vagueness through the steering, and a test drive should include tight turns at low speed to expose any rack wear. The electrical and lighting defects from the October 2025 failure are likely to have been rectified, but the buyer should verify that the windscreen washer system, wiper mechanism, dipped beam headlamp, and central stop lamp are all functioning correctly at the time of viewing, as intermittent electrical faults are common on older Mercedes-Benz vehicles of this era. Tyre condition warrants particular attention, with multiple advisories over several years relating to perishing and cracking on both front and rear axles, including a Dangerous defect for exposed cords in 2023 and run-flat damage in 2024; any tyres older than five years should be replaced regardless of tread depth due to age-related rubber degradation. The rear exhaust mounting defect recorded in both 2023 and 2025 suggests an intermittent or persistent issue that should be inspected for exhaust movement or unusual cabin noise. Finally, given the age of the vehicle, the buyer should verify the service history for recent replacement of the 12V battery, brake fluid, coolant, and hydraulic fluid for the convertible roof mechanism, as time-based fluid degradation can cause operational failures even on a low-mileage example, and any standing corrosion on the brake discs should be checked by driving the car and confirming smooth retardation without judder or pulling.
