2007 Mercedes-Benz B-Class 1.7L Petrol · BP57 AEJ

The vehicle presents a worsening maintenance trend, characterized by an increasing frequency and variety of mechanical defects in recent years. While the December 2025 test at 113,079 miles resulted in a pass, the tester flagged several immediate concerns including a minor front exhaust leak, a corroded nearside rear coil spring, and a severely deteriorated offside front CV boot. The presence of light oil misting on the offside front shock absorber and thinning front brake pads suggests that while the car remains legally roadworthy, the frequency of component failure is accelerating. The mileage profile shows a consistent, low-intensity usage pattern, averaging approximately 5,952 miles per year over its nineteen-year lifespan. This low annual mileage is evident in the progression from 74,536 miles in April 2019 to 113,079 miles in December 2025. However, the data reveals that low usage has not prevented age-related degradation. Instead, the vehicle shows a clear pattern of long-term environmental wear, particularly regarding rubber components and metal surfaces, which is common in vehicles that may spend significant time stationary. A prospective buyer must prioritise a thorough inspection of the braking system and underbody integrity. The MOT history shows a persistent, multi-year issue with corroded brake pipes and hoses, dating back to at least 2019 and continuing through the 2024 test. The recurring mentions of fuel pipe corrosion and surface rust on the underbody suggest that structural oxidation is a significant factor. The tester also noted signs of surface rust on various components in the November 2024 test, which warrants close scrutiny to ensure corrosion has not progressed to a structural level. The suspension and steering systems also require careful physical examination. The record identifies a long-standing trend of deteriorating dust covers on ball joints and anti-roll bar linkages, alongside previous issues with steering rack play. Given the recent reports of a corroded coil spring and deteriorating CV boots, the buyer should check for any signs of play in the suspension bushes or excessive movement in the drivetrain. The combination of aging rubber seals and ongoing corrosion indicates that while the car is functional, it is entering a phase of life where more frequent and costly mechanical repairs to consumables and suspension components are likely.
