2003 Mercedes-Benz E 5.4L Petrol · XLJ 750X

The vehicle currently holds a clean roadworthiness status, passing its most recent inspection in September 2025 at 125,357 miles with no recorded defects. The maintenance trend shows significant improvement following a mechanical failure in late 2023. Since that failure, the car has undergone two consecutive tests without advisories or failures, suggesting that the previous emissions issues were addressed and the vehicle is currently in stable condition. At 23 years old, the recorded mileage of 125,357 miles is notably low, averaging approximately 5,450 miles per annum. The data shows consistent usage in recent years, with only 1,492 miles driven between the 2024 and 2025 tests, and 1,002 miles between late 2023 and 2024. This low annual mileage often reduces wear on the drivetrain and engine internals but can lead to the degradation of rubber components and seals if the vehicle sits stationary for long periods. The failure in September 2023 at 122,851 miles highlighted critical issues involving a modified nearside exhaust catalytic converter and high carbon monoxide emissions. While the vehicle passed the subsequent tests, a buyer must verify that the exhaust system is now fully compliant and that the engine is burning cleanly. Given the age of the Mercedes and the low mileage, a physical inspection should focus on structural corrosion in the sills and suspension mounting points, as well as the condition of rubber bushings and brake hoses which perish over time regardless of distance driven.
