2018 Mercedes-Benz S-Class 2.9L Diesel · HMZ 311

The most recent MOT test on 19 March 2026 shows the vehicle passed, but the maintenance trend shows signs of declining attention to consumables. While the 2024 and 2025 tests recorded no defects, the March 2026 inspection flagged three separate advisories for tyres. The nearside front, offside front, and nearside rear tyres were all noted as being worn close to the legal limit or worn on the edges. This follows a previous failure in March 2023, where the offside front tyre tread depth fell below the 1.6mm legal requirement. The vehicle has covered 111,761 miles over its eight-year lifespan, averaging approximately 13,970 miles per year. This represents a higher-than-average annual mileage for a premium saloon of this age. The MOT history shows consistent annual testing, with the most recent test occurring five months prior to the current date. The mileage accumulation suggests regular use, which typically correlates with increased wear on suspension components, braking systems, and drivetrain elements. A prospective buyer should focus on the condition of the tyres and wheel alignment. The recurring issues with tyre wear, specifically the edge wear noted in 2026, may indicate underlying suspension geometry problems or worn bushes. The 2023 failure also noted thin rear brake pads, so a physical inspection of the remaining brake pad thickness and the condition of the brake discs is necessary. Given the high mileage and the recent advisories, checking the integrity of the suspension system and the condition of all four tyres is a priority. buying_score: 55 risk_level: Medium.
