2021 Mercedes-Benz GLA 200 AMG Line Executive D A 1.9L Diesel · KP71 SRV

The vehicle most recently passed its MOT on 5 September 2025 with no defects or advisories recorded, which represents the strongest possible outcome from a roadworthiness standpoint. Evaluating the broader trend across the available DVSA history, the maintenance profile is essentially stable and reassuring. The only recorded failure occurred on 14 September 2024 against an offside rear seat belt buckle not functioning as intended, but a retest on 17 September 2024 returned a pass, indicating that the defect was rectified promptly rather than being a persistent or structural concern. There are no advisories logged across any of the three recorded tests, and with no recurring component defects, no advisory progression, and no reappearances of previously flagged items, the trajectory is consistent with a well-maintained example rather than one showing deteriorating mechanical condition. The recorded mileage of 35,733 miles over approximately five years equates to around 7,150 miles per year, which is broadly typical for a vehicle of this age and class. This figure is consistent with regular but modest usage, most likely a mix of commuting and shorter journeys, and there is no evidence of either excessively high motorway mileage or prolonged periods of standing. Moderate annual mileage of this nature tends to be relatively kind to major drivetrain components such as the diesel engine, automatic transmission, and turbocharger, while still ensuring that consumables like brake discs, pads, and tyres are exercised regularly enough to avoid corrosion-related seizing. The absence of large mileage gaps between MOT readings further suggests continuous use rather than long-term storage, which is generally favourable for overall mechanical health. Given the clean MOT history and modest usage, a prospective buyer should focus on age- and calendar-related deterioration rather than chasing specific component defects already flagged by the tester. Diesel models of this vintage are particularly sensitive to time-based servicing, so it is essential to verify that the diesel particulate filter has been regularly regenerated, ideally through sustained running, and that the most recent oil and filter change, along with the timing belt or chain service interval as applicable, has been carried out to schedule. Brake discs on vehicles that have seen light urban use can develop surface corrosion from standing or short trips, so during a test drive, listen for any scraping, binding, or uneven pulling under light braking, and check for hot spots or juddering on a more decisive stop. Likewise, the rear seat belt buckle should be physically checked to confirm smooth release and re-engagement, as the 2024 failure history indicates this area warrants confirmation. Additional physical inspection points should include the condition of the tyres, particularly the sidewalls and tread shoulders, as even low-mileage tyres deteriorate through age-related perishing and UV exposure over a five-year period. Check the production date markings on the sidewalls and consider replacement if the rubber shows cracking regardless of remaining tread depth. The 12V battery is another calendar-sensitive component that often fails without warning on vehicles of this age, so a load test or verification of recent replacement is worthwhile, especially if the car has been used for predominantly short journeys. Finally, inspect the underside and wheel arch liners for any signs of fluid weeping from the diesel fuel system, suspension components, or air conditioning condensate lines, and verify that the full Mercedes-Benz service book and digital service history are present and stamped in line with the manufacturer schedule, as this will be a key factor in maintaining residual value and confirming that the apparent mechanical stability reflected in the MOT record is supported by consistent documented maintenance.
