2023 Mercedes-Benz GLB 220 AMG Line Prem D 4M A 1.9L Diesel · HN23 KPR

The Mercedes-Benz GLB 220 AMG Line Premium D presents a clean and stable roadworthiness record in its most recent MOT test on 13 March 2026 at 12,158 miles, where no defects were recorded. This suggests that, at least in the immediate term, the vehicle meets all DVSA safety and emissions standards without any outstanding mechanical failures or advisories. The absence of defects in this test—just four months prior to the current date—indicates that the car has passed a rigorous inspection covering structural integrity, braking efficiency, lighting, and emissions compliance. However, the brevity of the available MOT history means this verdict is based on a single snapshot rather than a longer-term trend, so a buyer should treat this as a starting point rather than definitive assurance of ongoing reliability. The vehicle’s mileage of 12,158 miles over approximately three years (2023–2026) is notably low, averaging around 4,053 miles per annum, which is well below the UK fleet average for a vehicle of this age. Such low mileage could imply either careful, infrequent use or prolonged periods of inactivity, potentially affecting fluid condition, battery health, and rubber components like suspension bushes or hoses. Without prior MOTs to compare, there’s no evidence of rapid mileage accumulation or neglect, but the lack of historical data means a buyer cannot rule out deferred maintenance simply because it hasn’t yet surfaced in official tests. The clean MOT record does not, however, confirm whether the car has been consistently serviced according to Mercedes-Benz’s schedule for this model. Given the sparse MOT history, a prospective buyer should prioritise a thorough pre-purchase inspection, particularly focusing on components prone to wear under low-mileage but prolonged storage conditions. Key areas to scrutinise include the suspension—specifically coil springs, anti-roll bars, and bushings—for signs of corrosion or degradation, as these can stiffen or fail even with minimal use. The braking system, including calipers, pads, and discs, should be checked for binding, uneven wear, or fluid leaks, especially if the car has sat unused for extended periods. Fluid levels—engine oil, brake fluid, coolant, and differential—should be verified, as stagnation can lead to contamination or seal deterioration. Additionally, inspect the battery for voltage and signs of sulphation, and examine rubber seals, hoses, and wiper blades for cracking or dry rot. While the MOT record offers reassurance on immediate roadworthiness, these checks will reveal whether the vehicle has been maintained proactively or left to deteriorate between tests.
