2019 Mercedes-Benz G 4.0L Petrol · LC69 MMU

The most recent MOT test on 14 October 2025 resulted in a clean pass with no defects or advisories recorded, which represents the strongest possible outcome from a roadworthiness perspective. Looking back across the available DVSA history, the vehicle has passed every annual test consecutively since 2022, with only one prior test in October 2024 carrying a small cluster of advisories. These older items have not reappeared at subsequent testing, suggesting they were addressed and that the overall maintenance trajectory is stable rather than deteriorating. A clean pass following a year with minor advisories is a positive indicator that the keeper has acted on previously flagged items and maintained the vehicle to a consistent standard. With 21,494 miles recorded over approximately seven years, this Mercedes-Benz G-Class shows an annualised mileage of only around 3,071 miles, which is substantially below the typical average for a vehicle of this age. While low mileage generally implies less mechanical wear on high-cycle components such as the clutch, brakes, and engine internals, it also carries specific risks associated with prolonged standing. Vehicles that spend extended periods stationary often suffer from degraded rubber components, fluid separation or contamination, and corrosion of brake friction surfaces due to infrequent use. Any prospective buyer should be alert to the possibility that this G-Class may have sat unused for long stretches, which can mask developing issues until the vehicle is put back into regular service. Given the clean MOT history and very low recorded mileage, age-related degradation becomes a more relevant concern than traditional wear items. The tyres should be carefully inspected for sidewall cracking, perishing, and tread hardening from age rather than purely from mileage, as rubber compounds deteriorate over calendar years regardless of use. The 12V battery should be load-tested, as batteries that have sat partially discharged for prolonged periods often suffer reduced capacity, and any standing-related issues with the auxiliary systems should be ruled out. Brake discs are particularly susceptible to corrosion from infrequent use, so a thorough check for binding calipers, uneven pad wear, and surface rust on the discs is essential, along with confirmation that the handbrake mechanism operates freely. Brake fluid should be tested for water content and replaced if more than two or three years old, as it is hygroscopic and degrades on a calendar basis irrespective of mileage. On a test drive, listen carefully for any suspension clonks or knocking from the bushes, coil springs, and anti-roll bar links, as components that have sat loaded in one position for long periods can seize or develop play. Pay particular attention to smooth operation of all four-wheel-drive and differential systems, which require regular use to remain lubricated and free of moisture contamination in the transfer box and axle housings. Inspect the underside and engine bay for any residual oil seepage, referencing the advisory noted on the 2024 test regarding a non-excessive oil leak, and confirm it has not worsened. Finally, verify the full service history with documented stamps at the correct intervals, and consider a precautionary replacement of the engine coolant, transmission fluid, and differential oils if there is any doubt about their age, as these time-sensitive fluids are often overlooked on low-mileage vehicles.
