2014 Mercedes-Benz G-Class 3.0L Diesel · G2 KOO

The 2014 Mercedes-Benz G-Class presents a currently roadworthy status, having passed its most recent MOT on 3 July 2025 at 55,719 miles with no defects recorded. The maintenance trend appears stable on paper, though the test history shows two anomalous failures in 2023 and 2025 where the tester issued no defects, implying administrative or presentation errors at the testing station rather than genuine mechanical faults. Recorded mileage stands at 55,719 against an eleven-year lifespan, averaging roughly 4,600 miles per year. The vehicle covered 9,367 miles between the September 2022 test at 36,245 miles and the October 2023 test at 45,612 miles, then added only 10,107 miles across the following twenty-one months to the July 2025 pass. Such low, uneven accumulation suggests extended periods of inactivity, which on a heavy 4x4 chassis invites corrosion to underbody members and seized suspension bushes through standing. The repeated no-defect failures on 11 October 2023 and 6 June 2025 prevent any technical fault trend from being drawn, but the absence of advisories across all five entries is unusual for a vehicle of this age and weight. A buyer should physically inspect the structural integrity of the ladder frame and outriggers for rust, given the low-use pattern, and verify the front coil springs and steering linkage for perishing from disuse. Brake discs and calipers warrant a road test to confirm no binding after standing, and the drivetrain oils should be checked for condensation contamination. The clean record demands independent verification rather than assumption of faultless care.
