2010 Mercedes-Benz S-Class 3.7L Diesel · CT60 YLU

The 2010 Mercedes-Benz S-Class presents a limited MOT record that offers little reassurance about its current mechanical condition. The most recent test, a pass recorded on 12 May 2022 at 143,505 miles, showed no defects whatsoever. However, this certificate is now over four years old, meaning there is no verified evidence of roadworthiness for a substantial period. The preceding test on 11 May 2022 at the identical mileage also recorded no defects, suggesting the vehicle was presented in a maintained state at that time. Without any subsequent testing, the maintenance trend cannot be classified as stable, improving, or worsening; it simply cannot be assessed beyond that 2022 snapshot. The mileage pattern raises questions rather than providing clarity. Both 2022 tests logged exactly 143,505 miles, indicating the vehicle was driven minimally between the failed and retest the following day. More critically, no further mileage data exists after May 2022. For a car now sixteen years old, this absence of recorded use over four years points to either very light usage or prolonged periods of standing. Either scenario carries implications. Low annual mileage around the typical 8,969-mile average for its age would be unremarkable, but a multi-year gap in testing leaves the true service history opaque. A buyer cannot determine whether the car has covered negligible miles since 2022 or has been driven regularly without the required certification. A physical inspection should prioritise the areas most vulnerable to deterioration during static storage or infrequent use. The S-Class of this generation is known for air suspension faults, so the Airmatic struts and compressor require close examination for leaks or failure to maintain ride height. Brake calipers can seize and discs can corrode superficially when a vehicle sits unused, so a thorough check of the braking system is essential. Tyres must be inspected for flat spots, perishing, and date codes, as rubber degrades with age regardless of tread depth. The exhaust system, rubber bushings, and coolant hoses also merit scrutiny for deterioration that MOT testing would normally flag. Given the absence of any recorded advisories or defects in the available history, there is no evidence of recurring mechanical faults. However, the lack of recent certification means a buyer is purchasing without the safety net of a current MOT. A pre-purchase inspection by a specialist familiar with the W221 S-Class platform is strongly advisable before committing, particularly to assess structural corrosion around the subframes, sills, and wheel arches, which can develop unnoticed when a vehicle is not regularly examined under test conditions.
