2022 Mercedes-Benz GLB 200 AMG Line Premium + A 1.3L Petrol · KM72 LFG

Consistent tyre degradation represents the primary mechanical concern for this vehicle, as evidenced by the advisories issued during the most recent MOT test on 2 September 2026. While the vehicle successfully passed its inspection, the presence of perishing and cracking on all four tyres indicates that the rubber compounds are showing signs of age-related fatigue despite the relatively low usage. This development follows a clean pass in October 2025, suggesting that the current condition of the tyres is a recent progression that requires immediate attention to ensure road safety and handling precision. Accumulating approximately 19,723 miles over four years results in an average of roughly 4,931 miles per annum, a figure that sits well below the typical usage profile for a modern SUV. This low-mileage history suggests the vehicle has spent significant time stationary, which can lead to specific mechanical considerations regarding the condition of rubber components and seals. While the drivetrain has not yet reached the high-mileage thresholds where major component fatigue typically occurs, the infrequent use necessitates a thorough check of all flexible materials that may have hardened or deteriorated during periods of inactivity. Given the specific advisories regarding tyre perishing, a prospective buyer should prioritise a physical inspection of the tyre sidewalls and tread blocks for signs of dry rot or structural compromise. During the test drive, pay close attention to any vibration through the steering wheel or unusual road noise at varying speeds, as these can be symptomatic of uneven tyre wear or carcass deformation resulting from prolonged periods of standing. It is essential to verify that the tyres are not only within the legal tread depth limit but are also free from deep cracks that could compromise their integrity under load or at motorway speeds. Beyond the tyres, the test drive should involve a focused assessment of the suspension and braking systems to ensure that the low-mileage profile has not resulted in seized or stiffened components. Listen carefully for any knocking or clunking sounds when traversing uneven road surfaces, which could indicate that suspension bushes or linkages have stiffened or perished due to lack of regular movement. Additionally, observe the brake pedal feel for any signs of sponginess or hesitation, and check for any pulling to one side during firm braking, which would suggest that the callipers or sliding pins may require lubrication or service following their limited use.
