2008 Mercedes Unknown 3.0L Heavy oil · RX08 CEF

The vehicle maintains a roadworthy status, having passed its most recent MOT on June 12 2026 at 30,674 miles with no recorded defects. The maintenance trend appears stable, despite an unexplained failure in September 2025 at 30,326 miles where no specific defects were logged, suggesting an administrative error or a rapid retest. Since that anomaly, the car has consistently met minimum safety standards across the last several tests. The mileage profile is exceptionally low for an 18-year-old vehicle, averaging approximately 1,700 miles per year. Data shows consistent low-usage patterns, such as the only 1,327 miles driven between September 2024 and September 2025, and 348 miles between annual tests. While low mileage reduces mechanical wear on the engine and drivetrain, such long periods of standing often lead to degradation of rubber components, dry seals, and corrosion on braking surfaces due to a lack of heat and friction operation. A physical inspection should focus on the exhaust system, which showed recurring minor gas leaks in July 2019, 2020, and 2022. While these did not cause failures, the persistence of the issue suggests thinning or failing gaskets that may require attention. The buyer should also examine the brake discs, as the 2017 test flagged pitting and scoring on both front units. Given the low usage, check for surface rust on the rotors and seized calipers, and ensure the ESP light reported in 2016 has been properly verified as resolved.
