2003 Mercedes-Benz CLK 2.6L Petrol · BD53 TFF

The latest MOT test passed on 12 November 2025, but the recent inspection history indicates a deteriorating maintenance trend. While the vehicle showed no defects in late 2023 and 2024, the 2025 testing period revealed a significant decline in roadworthiness, including a dangerous failure for insufficient tyre tread depth and a major failure for a lighting defect. The presence of multiple advisories regarding suspension components and tyre wear suggests that the vehicle is entering a phase of increased mechanical degradation, moving away from the stable condition observed in the previous two years. With a recorded mileage of 229,452 miles over approximately 23 years, the vehicle has averaged nearly 10,000 miles per year. This usage pattern is typical for a vehicle of this age and suggests regular, consistent operation rather than long periods of inactivity. However, the high total mileage necessitates a cautious approach, as the cumulative wear on the engine, drivetrain, and chassis components will be substantial. While regular use helps prevent certain types of corrosion and seal drying, the sheer volume of mileage means that consumables such as suspension bushes, dampers, and various seals are likely nearing the end of their functional lives. Prospective buyers should pay close attention to the suspension and steering during a test drive. The MOT history specifically highlights issues with nearside rear shock absorber damping and various suspension arm bushes and ball joints. You should listen for any rhythmic knocking, clunking, or creaking sounds when driving over bumps or during low-speed maneuvering. A failing shock absorber may result in excessive rear-end bounce or a lack of stability during cornering. Furthermore, inspect the tyres for uneven wear patterns, particularly on the inner or outer edges, as this is a common symptom of the worn suspension geometry and tracking issues noted in the recent advisories. Immediate attention should be given to the advisory regarding the nearside rear shock absorber, which will require replacement to restore proper handling characteristics. Given the vehicle's age and high mileage, it is also vital to inspect the underside for signs of structural corrosion and to check the condition of all rubber-to-metal mounting points for perishing. Ensure that the brake system is free from binding calipers and that the discs do not show excessive pitting or thinning. Finally, verify the service history to confirm that fluid-based maintenance, such as brake fluid and coolant replacements, has been carried out on a calendar-based interval to prevent internal degradation.
