2017 Mercedes-Benz S-Class 5.5L Petrol · X44 AAA

The 2017 Mercedes-Benz S-Class passed its most recent MOT on 20 January 2026 at 41,610 miles, with no failures recorded across the five tests on file. The maintenance trend appears stable, showing a clean pass record throughout the documented history. Two advisories were issued at the latest test relating to tyre condition, while the intervening 2025 test returned a clean sheet with no defects noted. The absence of any structural, brake, suspension, or corrosion advisories across the entire dataset is a positive technical indicator, though the recurring tyre wear flags warrant closer inspection. Annual mileage equates to roughly 4,623 miles, which is substantially below the typical usage for a nine-year-old vehicle of this class. The record shows a notable gap between the January 2025 test and the January 2026 test, with the odometer advancing only around 3,000 to 4,000 miles across that year, consistent with the low overall average. The largest single-year gap appears between February 2023 and December 2023, where only a modest mileage increment is implied. Sparse annual accumulation such as this can reflect light use, but extended standing periods can bring their own concerns, particularly regarding brake disc corrosion, dried seals, and tyre deterioration from prolonged static load. The advisory at the January 2026 test for nearside rear tyre wear on the edge, combined with a nail in the offside rear tyre, indicates that the rubber may have been nearing the end of its useful life at the time of test. A near-identical advisory was issued in December 2023 for nearside front outer tyre edge wear, suggesting that uneven shoulder wear has been a recurring characteristic across two separate tyres on different axles. A pre-purchase inspection should include a close check of current tyre condition, wheel alignment, and any signs of tracking issues causing the consistent edge wear pattern. Buyers should also physically inspect components not fully visible on a standard MOT hoist. The February 2023 advisory noted that undertrays and covers were obscuring some components, which limits what the tester could evaluate that year. A thorough inspection should therefore examine the brake discs for surface corrosion, the coil spring condition, and the exhaust system for any mounting deterioration consistent with low-mileage, long-interval use. Confirming recent brake fluid and coolant service dates would also be prudent given the low annual mileage recorded.
