2018 Mercedes-Benz S-Class 2.9L Diesel · KA18 ALA

The vehicle currently maintains a stable roadworthiness status, following a clean pass in its most recent inspection on March 2 2026 at 99,852 miles. The maintenance trend appears consistent over the last four years, as the vehicle only experienced a single recorded failure in February 2025, which was immediately rectified to pass on the same day without further defects. This suggests the previous owner was proactive in addressing immediate mechanical requirements rather than allowing minor faults to accumulate. The mileage profile indicates high usage for an eight-year-old luxury saloon, averaging approximately 12,500 miles per annum. There is a significant surge in activity between November 2022 and March 2024, where the car covered over 10,000 miles in just sixteen months. The rate of accumulation remained high, with another 15,000 miles logged between February 2025 and March 2026. This consistent high-mileage pattern places greater strain on complex drivetrain components and sophisticated air suspension systems typical of the S-Class compared to lower mileage examples. A buyer should focus their physical inspection on the air suspension bellows and rubber bushings, as high mileage often leads to perished rubber and air leaks in these areas. While the MOT record shows no structural corrosion issues, the frequent use justifies a thorough check of brake disc thickness and caliper condition for uneven wear. Given the vehicle is approaching the 100,000-mile mark, verifying the integrity of the gearbox service and checking for fluid leaks is essential to ensure the high mileage has not resulted in deferred mechanical maintenance.
