2009 Mercedes-Benz B200 Sport CDI Auto 2.0L Diesel · KM09 HFB

The vehicle is currently roadworthy, following a clean pass in March 2026 at 51,045 miles. The overall maintenance trend shows a marked improvement after a period of significant neglect. While the 2023 and 2024 tests revealed multiple failures related to corrosion and worn components, the 2025 and 2026 records indicate no remaining defects, suggesting the current owner has addressed the critical mechanical and structural issues identified in previous years. The mileage profile is exceptionally low for a 17-year-old vehicle, averaging approximately 3,000 miles per year. There is a notable gap in usage between May 2024 and January 2025, where the car covered only 728 miles in eight months. This low-frequency use explains the presence of perished tyres noted in early 2025, as rubber compounds degrade over time regardless of distance driven. However, such long periods of standing often lead to the specific issues seen in this history, such as moisture retention causing corrosion rather than mechanical wear. A physical inspection must focus on the structural integrity of the rear subframe and brake lines. The 2024 test flagged corrosion on the rear subframe and the offside front brake pipe, and while these passed subsequently, rust is progressive. One must verify that no new structural thinning has occurred. The buyer should also check the rear shock absorbers, which were noted as corroded in 2024, and ensure the nearside front brake remains free of the binding that caused a failure in three years prior. Given the history of perished rubber, checking the sidewalls of current tyres for cracking is essential to ensure they are not age-rotted.
