2007 Mercedes-Benz SLK 3.0L Petrol · KA07 EKB

A notably thin MOT paper trail defines this 2007 Mercedes-Benz SLK, with all five recorded tests clustered within an unusually tight fourteen-month window between November 2024 and December 2025, and three of those visits ending in failure despite no advisory or defect entries being recorded against the vehicle. The two-day turnaround between the 15 December 2025 failure and the 17 December 2025 pass suggests a quick remedial repair rather than any fundamental structural or mechanical concern, and the absence of any documented advisories across either successful test means there is no DVSA evidence of wear items approaching their replacement threshold. For a car approaching its twentieth year, this clean advisory record is unusual and could equally reflect a lightly used modern classic or, conversely, a vehicle that has spent considerable time off the road between tests rather than one that has been driven continuously and diligently maintained. The recorded odometer reading of 109,862 miles against a 2007 registration equates to an annual accumulation of roughly 5,782 miles, which is comfortably below average for a nineteen-year-old vehicle and well below the typical 7,000 to 10,000 miles most SLKs of this generation would have covered. Such a modest figure can be interpreted in two ways. On one hand, low annual mileage reduces wear on major drivetrain components, clutch material, brake friction surfaces and suspension bushes, which would be consistent with the clean advisory history. On the other, extended periods of low use or standing can bring their own concerns around seized callipers, dried perished rubber boots and bushes, and dry-rotted flexible brake hoses and fuel lines, none of which would necessarily be captured on a static MOT ramp check. Because the MOT history contains no component-specific advisories to reference, a prospective buyer should focus the physical inspection on areas commonly affected by age and standing time in this generation of SLK, regardless of the favourable paper trail. With the retractable hard-top roof, check the operation of the roof mechanism through a full cycle, listening for any grinding or hesitation from the hydraulic rams, and inspect the fabric or rubber seals around the roof aperture and door shuts for perished sections that could allow water ingress into the boot and electric roof modules. Examine the underbody and wheel arches closely for surface corrosion on the subframe, suspension arms and the heat-shielded sections around the exhaust, as nineteen years of British weather will have taken a toll even on a low-mileage example, and check the inner and outer sills plus the rear wheel arches for any bubbling paint that might indicate structural corrosion developing beneath the surface. On the test drive, pay particular attention to the feel of the suspension over uneven roads, listening for clonking or knocking from the front lower wishbones and anti-roll bar bushes, which are known to perish on these models, and any vagueness or knocking through the steering that could point to top mount or steering rack wear. Feel for any pulling to one side under braking, which would suggest a binding slider caliper or a warped front disc, and listen for any rubbing or scraping noises from the rear calipers and handbrake mechanism, which seize readily if the car has spent long periods stationary. Finally, verify that the engine cooling fan cuts in promptly when the air conditioning is engaged, as SLKs of this era are prone to auxiliary coolant leaks and slow leaks from the radiator and expansion tank that may not be obvious on a short stationary inspection but would be relevant to a car that has covered its miles in short, low-speed trips rather than sustained running.
