2016 Mercedes-Benz S-Class 6.0L Petrol · S 600

The most recent DVSA examination on 6 November 2025 resulted in a pass, though two advisories were issued concerning the nearside and offside front tyres being worn close to the legal limit and on their edges. These advisories represent the only recorded defects in a five-year MOT history, with each test from 2021 through 2024 returning a clean pass with no advisories whatsoever. While the absence of advisories prior to 2025 could suggest a well-maintained vehicle, the sudden appearance of two related tyre issues on the same axle indicates that wear has progressed to a point where replacement is now due. The overall trend remains broadly stable rather than worsening, as there are no structural, braking, or suspension advisories present, but the front axle tyre wear warrants immediate attention before further use. The recorded mileage of 13,536 miles over a ten-year period equates to an average annual usage of approximately 1,354 miles, which is exceptionally low for any motor vehicle, particularly a luxury saloon of this calibre. Such limited use typically reflects a vehicle that has spent considerable time stationary rather than being driven regularly. While low mileage generally preserves engines, transmissions, and major mechanical components from wear-related fatigue, prolonged standing creates its own distinct set of mechanical concerns. Brake discs and calipers are prone to surface corrosion and seizing when not used regularly, rubber components deteriorate through oxidation rather than wear, and drivetrain seals can harden and leak due to lack of regular thermal cycling. Given the low usage profile, a prospective buyer should pay particular attention to age-related degradation rather than wear-related issues. The front tyres, which were already approaching the legal limit despite minimal mileage, should be inspected for sidewall perishing and cracking, as ten-year-old rubber compounds harden and lose elasticity regardless of tread depth. The 12-volt battery is likely to be original or long-standing and should be load-tested, as low-use vehicles frequently suffer from sulphation and premature battery failure. All brake calipers, particularly those on the rear axle which bear less load, should be examined for binding, and the brake discs checked for severe corrosion pitting, as standing vehicles develop rust that can lead to juddering or ineffective braking on the first applications. Fluid servicing should be verified independently of the MOT record, as time-based degradation occurs regardless of mileage. Brake fluid is hygroscopic and typically requires renewal every two to three years to prevent internal corrosion of the ABS modulator and brake caliper bores, meaning at least three renewals will be due based on age alone. Engine oil and filter changes may have been infrequent due to low mileage, allowing moisture and combustion by-products to accumulate, so a fresh service is advisable upon purchase. Coolant, transmission fluid, and differential oil all degrade with calendar age, and verifying the service history stamps alongside a comprehensive inspection by a Mercedes-Benz specialist is strongly recommended. During a test drive, listen for any suspension clonks over uneven surfaces, check for pulling under braking which may indicate a seized caliper, and ensure the transmission shifts smoothly, as low-mileage automatic gearboxes can develop torque converter and mechatronic issues when not regularly exercised.
