2021 Mercedes-Benz AMG GLS 63 NT ED Exec MHEV4M+A 4.0L Hybrid electric (clean) · LR71 XBU

The DVSA test history for this 2021 Mercedes-Benz AMG GLS 63 shows a consistently clean roadworthiness profile across both recorded assessments, with the most recent pass at the anniversary test on 5 September 2025 and a prior pass on 30 August 2024, each free of advisories or failures. For a high-performance, four-wheel-drive luxury SUV with a complex air suspension and hybrid mild-electric drivetrain, the absence of flagged component wear over successive tests is notable. Vehicles of this class typically attract advisories for early-disc wear, corrosion under the wheel arches, or suspension component degradation, yet none have surfaced. The MOT record therefore reads as a stable and uninterrupted compliance history, though buyers should recognise that MOT testing only samples externally inspectable items at one point in time and does not interrogate the engine, transmission, or hybrid ancillaries. The recorded mileage of 39,506 miles over a five-year span equates to roughly 7,900 miles per year, which is broadly typical for a luxury SUV used as occasional family or long-distance transport rather than a high-mileage workhorse. The fact that only two MOT entries appear from the fourth year of registration onwards is consistent with a vehicle that was first tested at the three-year threshold and has been in regular use throughout. This annual accumulation rate suggests moderate but not punishing use, which generally preserves brake discs, air suspension bellows, and tyre life, though the considerable kerb weight and performance output of this AMG variant still place meaningful thermal and mechanical load on the braking system, driveline, and tyres even at modest mileages. For a prospective buyer inspecting this vehicle today, the absence of recorded advisories means there are no specific flagged components to target, but the test drive should nonetheless focus on the items most likely to develop issues on a heavy performance SUV of this age and specification. Listen for any creaks, clonks, or thuds from the front and rear suspension over speed humps and uneven surfaces, as air-spring leaks or failing self-levelling components are common on MHEV platforms and often present before any warning light appears. On the move, the steering should feel precise without vibration through the rim, and the brake pedal should offer firm, consistent response without judder under firm application, which would suggest warped front discs. At low speed, apply the brakes evenly to confirm there is no pulling to one side, and check for any binding or dragging sensation from the front wheels once released, as large calipers on AMG braking systems can stick. Beyond the dynamic check, a careful static inspection is warranted. Examine the inner and outer faces of all four wheels for lipping on the disc edges and uneven pad wear, confirm the tyre shoulders are wearing evenly across both axles, and inspect the underside for any signs of fluid seepage from the air suspension struts, differential, or transfer case. Look closely at the brake flexibles and underbody piping for any surface corrosion or chafing, particularly given the winter salt exposure that UK SUVs typically endure. Finally, verify that all hybrid system warning messages clear on ignition and that the infotainment and driver assistance systems function correctly, as the MOT does not cover these areas but they are integral to the vehicle's overall mechanical and electrical integrity.
