2007 Mercedes S-Class 3.0L Diesel · CU07 KUD

The most recent DVSA examination on 2 December 2025 recorded a PASS with no defects or advisories, indicating that the vehicle met the statutory roadworthiness requirements at the time of test. The earlier records show three further PASS outcomes on 24 November 2021, 29 November 2022, and the most recent 2025 test, with the sole FAIL entry dated 16 November 2021 being followed by a PASS just eight days later on 24 November 2021, strongly suggesting a straightforward repair and re-test rather than a fundamental mechanical issue. Across the visible DVSA history there are no advisories flagged for any component, which on the surface portrays a stable and well-maintained vehicle. Nevertheless, the complete absence of advisories on a nineteen year old luxury saloon is uncommon and may reflect either meticulous upkeep, prompt rectification prior to test, or limited mileage accumulation between examinations, all of which warrant closer physical verification. The recorded odometer reading of 106,708 miles against an approximate nineteen year vehicle age equates to an annual usage rate of roughly 5,600 miles, which is substantially below the national average and markedly low for a car of this class. Such a figure implies either genuinely light motoring, extended periods of storage, or significant gaps between MOT tests where the vehicle may have been off-road and therefore not recorded for usage. The MOT intervals shown also support this interpretation, with a sizeable gap between the 2021/2022 tests and the next recorded examination in late 2025, during which the average annual mileage would be considerably lower than the lifetime figure. While low mileage preserves engines, gearboxes and drivetrain components from wear-related fatigue, prolonged standing periods introduce their own mechanical concerns including internal corrosion, dried seals, fluid degradation and electrical gremlins, all of which are particularly relevant to a complex Mercedes S-Class with extensive electronic systems. Given the clean DVSA record and the low annual usage, a prospective buyer should focus inspection efforts on age and standing-related deterioration rather than high-mileage wear items. Tyres should be examined closely for sidewall perishing and cracking, as rubber compounds degrade with calendar age regardless of tread depth, and original specification replacements should be confirmed due to the cost of correctly sized premium tyres. Brake discs and calipers are prone to surface corrosion and binding when a vehicle is stored, so a test drive should include several firm brake applications from moderate speed to check for shudder, vibration or pulling, while the wheels should be spun by hand when cold to detect any caliper stiffness. The 12V battery and auxiliary systems warrant a health check, as prolonged standing and infrequent use rapidly deplete battery condition and can trigger warning lights or control module faults on the S-Class, and any history of replacement should be confirmed. Finally, time-based servicing must be verified independently of mileage, as low annual use does not exempt the vehicle from oil, filter, coolant, brake fluid, transmission fluid and air conditioning servicing intervals. Service book stamps or documented invoices should be inspected for evidence of annual or bi-annual maintenance regardless of odometer progression, and a compression test or diagnostic scan would be prudent to confirm internal engine health given the likelihood of short journeys and cold starts. Coolant hoses, pipework and the notoriously complex Mercedes air suspension system should be examined for perished rubber, fluid leaks and component corrosion, all of which are common failure points on the W221 chassis. A thorough pre-purchase assessment by a Mercedes specialist or independent German marque expert is strongly recommended to complement the reassuring DVSA record, ensuring that the clean MOT history translates into genuine mechanical integrity rather than merely reflecting infrequent use.
