2005 Mercedes-Benz B-Class 1.5L Petrol · RF55 XGL

Significant structural corrosion and recurring suspension issues define the mechanical profile of this Mercedes-Benz B-Class. While the vehicle achieved a pass on 28 October 2025, the preceding test on 27 October 2025 resulted in a failure due to a fractured offside rear coil spring and excessive corrosion on the nearside front upper suspension spring mounting turret top, which was flagged as a major defect reducing structural strength. The record shows a persistent trend of corrosion-related advisories, specifically regarding the metal fuel filler pipes and brake pipes, alongside intermittent failures involving suspension components and drive shaft boots. The vehicle has covered 92,025 miles over its 21-year lifespan, representing an average annual accumulation of approximately 4,382 miles. This low annual mileage suggests the vehicle has been used sparingly; however, the MOT history reveals a pattern of age-related degradation that is common with vehicles that may spend extended periods stationary. This is evidenced by the 2024 advisory for perished rear tyres and the recurring issues with rubber components, such as brake hoses and CV boots, which can degrade through lack of regular movement and environmental exposure rather than through high-mileage wear. Prospective buyers should pay close attention to the structural integrity of the chassis and suspension mounting points. The recent major failure regarding the nearside front upper suspension spring mounting turret top indicates significant metal wastage that requires thorough inspection. During a test drive, listen for any metallic knocking, clunking, or creaking sounds when traversing uneven surfaces or bumps, as these could indicate further degradation of the suspension bushes, coil springs, or ball joints. Additionally, monitor the steering for any pulling or instability, which may stem from the previously noted issues with suspension component dust covers and ball joints. The braking system and fuel delivery components also require scrutiny due to repeated advisories. The record notes deterioration in both nearside and offside front brake hoses, as well as historical corrosion on the nearside rear brake pipe and both metal fuel filler pipes. On a test drive, check for any sponginess in the brake pedal or a change in pedal feel, which could indicate compromised hydraulic lines. Furthermore, inspect the area around the fuel filler neck for signs of weeping or significant surface rust to ensure the integrity of the fuel system.
