2018 Mercedes-Benz GLA 2.1L Diesel · DA18 ABX

The Mercedes-Benz GLA has demonstrated a stable and clean roadworthiness record over the past three MOT cycles, with the most recent test on 17 March 2026 at 33,264 miles showing no defects—an outcome mirrored in the 2025 and 2023 passes . The only anomaly is the duplicate entry for 27 March 2024 , where the vehicle was tested twice at 28,036 miles , once failing and once passing without recorded faults. This discrepancy suggests a clerical error rather than a mechanical issue, as no defects were logged in either instance. The absence of advisories or failures in recent years indicates that major components—such as brakes, suspension, and structural integrity—have been maintained to a high standard. However, the lack of recorded mileage progression between the 2024 and 2025 tests (a gap of nearly 12 months with no mileage increase) raises questions about whether the vehicle was in regular use or stored during that period. The GLA’s mileage of 33,264 miles over eight years —averaging just 4,158 miles annually —is exceptionally low for its age, falling well below the UK average for a vehicle of this vintage. The stagnation between 28,036 miles (March 2024) and 30,226 miles (March 2025) is particularly striking, suggesting either infrequent use or an extended period of inactivity. If the car was stored, this could mean reduced wear on consumables like tyres and brakes, but it may also indicate potential issues with fluid degradation (e.g., brake fluid, coolant) or battery health due to prolonged disuse. The rapid mileage accumulation between 25,097 miles (March 2023) and 28,036 miles (March 2024) —an increase of 2,940 miles in a year —suggests a brief period of more active use, though this is still modest compared to typical urban driving patterns. Given the clean MOT history, a prospective buyer should prioritise a thorough inspection of components that are not routinely checked in standard MOT tests. Particular attention should be given to the brake system , including the condition of brake discs, pads, and calipers , as binding or uneven wear can develop without being flagged in basic tests. The suspension —specifically control arm bushes, coil springs, and anti-roll bars —should be checked for wear or corrosion, especially if the vehicle has spent extended periods in damp or salty conditions. While the MOT records show no structural defects, underbody corrosion and wheel arch rust are common in GLA models and should be visually inspected for signs of deterioration. Additionally, the exhaust system and emissions should be verified, as leaks or catalytic converter issues can arise without immediate MOT consequences. Finally, given the low mileage and potential storage periods, the battery health , fluid levels , and tyre condition —even if tread depth is legal—should be assessed, as these are less likely to have been regularly serviced.
