2007 Mercedes S-Class 3.0L Diesel · KK57 AJU

The vehicle was presented for its most recent DVSA MOT examination on 28 May 2026 and achieved a Pass outcome with no defects or advisories recorded against it. This represents the fifth consecutive annual pass, with identical clean results documented in each of the four preceding tests back to May 2022. The consistency of these outcomes, with no recurring advisory items relating to brake wear, suspension component deterioration, tyre condition, exhaust integrity, or structural corrosion, indicates a stable and well-managed maintenance trend. For a prospective buyer, this clean record provides reassurance that the vehicle has remained within prescribed roadworthiness tolerances at each annual inspection, although it is important to recognise that the MOT test is a point-in-time safety and emissions check rather than a full mechanical health assessment. With a recorded odometer reading of 80,001 miles against a vehicle age of approximately nineteen years, this Mercedes S-Class has covered an average of only around 4,200 miles per year. This figure is significantly below the typical annual mileage for a luxury saloon of this era and suggests either prolonged periods of storage, predominantly short-trip or low-intensity use, or a combination of both. While low annual mileage reduces wear on drivetrain components such as the engine, transmission, and final drive, it introduces a different set of mechanical considerations. Long-standing vehicles are particularly susceptible to calendar-based degradation of consumables and perishable components that age regardless of mileage accumulation. Given the clean MOT history and the low-mileage, older-vehicle profile, a prospective purchaser should undertake a series of age-appropriate checks beyond what the MOT documents can reveal. Tyres fitted to a vehicle of this age and standing time should be examined closely for sidewall perishing, cracking, and ozone-related degradation, as rubber compounds deteriorate through age even when tread depth remains adequate; any tyre older than approximately six years warrants careful scrutiny or replacement regardless of wear. The braking system should be inspected for surface corrosion on the brake discs, which can occur from standing, and the calipers should be checked for binding or seized pistons that may cause uneven pad wear or pulling under braking. The 12V battery, given the vehicle's age, is likely to be approaching the end of its service life and should be load-tested, as a depleted battery can cause electronic control unit faults in this model. Coolant, brake fluid, and automatic transmission fluid all degrade through calendar age rather than mileage, and verifying recent servicing of these fluids, along with evidence of cambelt or timing chain attention where applicable, is essential. On a test drive, particular attention should be paid to suspension refinement, listening for clonks or knocking from ageing bushes, coil springs, and anti-roll bar links, as well as monitoring the transmission for smooth and timely shifts given the Mercedes automatic gearboxes of this era can develop torque converter or valve body irregularities with age. Finally, a thorough underbody inspection is advisable to identify any emerging structural or chassis corrosion that may not have been flagged at MOT stage but could become an issue in the near future.
