2009 Mercedes-Benz B-Class 1.5L Petrol · KS09 EXA

The vehicle presents a stable and largely well-maintained roadworthiness profile. The most recent test on 27 August 2025 at 57,012 miles resulted in a pass, though the tester flagged two minor advisories. The nearside rear inner brake pipe showed corrosion obscured by grease or contamination, and the offside front shock absorber had a light oil misting. These are not immediate failures, but they indicate the car has begun to develop the kind of age-related deterioration typical of a 17-year-old vehicle. The trend is not worsening sharply, but it is no longer the clean record seen in previous years. The mileage pattern is notably low for a 2009 vehicle. Between the July 2022 test at 53,741 miles and the August 2024 test at 54,814 miles, the car covered just 1,073 miles over roughly two years. From August 2024 to August 2025, it added only 2,198 miles. This suggests extended periods of light use or standing. Low annual mileage around 3,354 miles per year reduces wear on drivetrain and braking components, but it can allow moisture to accumulate in brake lines and exhaust systems, and rubber bushes and seals to dry out or corrode from lack of regular heat cycling. The corroded nearside rear brake pipe is the most significant finding in the record. Brake pipe corrosion is a progressive issue, particularly on older Mercedes-Benz models where steel lines can deteriorate internally and externally, especially in areas exposed to road salt. The fact that the corrosion was obscured by grease or material suggests the pipe may not have been inspected closely during prior servicing. A buyer should have the entire brake line system inspected for wall thickness and pitting, paying close attention to rear axle areas and any underbody sections where moisture collects. The light oil misting on the offside front shock absorber is a common early-stage fault on aging suspension components. It does not indicate imminent failure, but it does suggest the damper seal is beginning to weep. Combined with the vehicle's age, a thorough inspection of all four shock absorbers, coil springs, and suspension bushes is advisable. The clean record from 2021 to 2023 shows the car was well cared for during that period, but the emergence of advisories in 2025 signals that deferred maintenance or natural deterioration is now catching up. A pre-purchase inspection focusing on structural rust, brake hydraulics, and front suspension components would be prudent.
