2021 Mercedes-Benz G 400 AMG Line Prem + D 4M A 2.9L Diesel · HOT 1Y

The vehicle’s most recent MOT test on 31 October 2025 confirms it remains roadworthy under current DVSA standards, with no defects or advisories recorded. This marks a stable maintenance trend over the past two tests, as the previous pass on 30 September 2024 also showed no issues. The absence of recurring faults suggests the vehicle has not experienced persistent mechanical failures, though this does not preclude hidden wear or deferred maintenance. The 2025 test occurred just 9 months ago, which is within the optimal window for a pre-purchase inspection, though a thorough examination remains essential given the vehicle’s age and mileage. The recorded mileage of 52,840 miles over five years—approximately 10,568 miles annually—falls within the typical range for a vehicle of this age. There are no evident gaps in service history to suggest prolonged neglect, nor does the mileage indicate aggressive use that might accelerate wear on suspension bushes, coil springs, or drivetrain components. The lack of MOT advisories or defects in either test implies no urgent mechanical concerns were overlooked by previous owners, though the absence of service records means critical intervals for fluid changes, timing belt inspection, or differential service cannot be confirmed. Given the clean MOT history, a buyer should prioritise an independent inspection of high-wear components such as the suspension bushes, rear wheel bearings, and brake calipers, as these are common failure points in AMG-line vehicles. The binding calipers or uneven brake wear advisories that occasionally plague this model should be checked, particularly if the vehicle has been driven aggressively. Structural corrosion, especially around wheel arches and underbody, warrants scrutiny given the vehicle’s age and exposure history. Finally, the exhaust system and catalytic converter should be examined for leaks or excessive corrosion, as these are frequently overlooked but critical to emissions compliance and structural integrity.
