2017 Mercedes-Benz G-Class 5.5L Petrol · MB67 SAJ

The 2017 Mercedes-Benz G-Class presents a clean MOT record with no advisories or failures recorded across both available tests. The most recent examination on 6 October 2021 passed with zero defects at 21,280 miles, indicating sound mechanical and structural condition at that point. The maintenance trend is stable, though the record is notably sparse for a vehicle now approaching nine years of age, with no test documented for over four and a half years as of June 2026. The mileage profile raises questions. Between the September 2020 test at 15,159 miles and the October 2021 test at 21,280 miles, the vehicle accumulated 6,121 miles in roughly thirteen months, a sharp increase compared to the prior period and the overall annual average of approximately 2,364 miles. Since October 2021, the recorded mileage has remained static at 21,280, suggesting the vehicle has either been driven very little or not at all for nearly five years. Prolonged standing poses its own risks, including flat-spotted tyres, deteriorated brake discs from surface corrosion, dried seals, and potential fuel system condensation. A buyer should treat the absence of recent MOT evidence as a caution rather than reassurance. The G-Class platform, with its body-on-frame construction, live axles, and substantial weight, is susceptible to suspension bush wear, steering linkage play, and underbody corrosion if left inactive. A thorough inspection of the chassis rails, differential housings, brake calipers for seizure, and tyre sidewalls for age-related cracking is essential. The engine and transmission should be assessed for cold-start irregularities and fluid leaks that can develop during extended dormancy. The single advisory noted in September 2020 regarding engine covers and under trays being fitted is minor but worth verifying, as missing shields can mask fluid leaks or allow debris ingress. Without a current MOT, the buyer assumes the risk of undetected deterioration, and a pre-purchase inspection by a specialist familiar with the W463 platform is strongly recommended.
