2003 Mercedes-Benz CLK 3.2L Petrol · EF03 MPZ

The 2003 Mercedes-Benz CLK presents a clean and stable maintenance trend, with the most recent MOT conducted on 12 February 2026 at 55,355 miles returning a pass with zero defects. This is the fourth consecutive clean test, following identical no-defect passes in February 2025, February 2024, and February 2023. The consistency of these outcomes across four years indicates that the vehicle has been maintained to a competent standard, with no recurring mechanical or structural faults emerging over the recorded period. The mileage accumulation is notably low for a vehicle of this age. Between the February 2022 test at 52,383 miles and the February 2026 test at 55,355 miles, the car covered just 2,972 miles over four years, averaging roughly 743 miles per annum in that window. Across the full recorded history, the annual average sits at approximately 2,407 miles. This pattern suggests prolonged periods of limited use, which can be a double-edged factor. Low mileage reduces wear on consumables such as brake discs, tyres, and suspension components, but extended periods of standing can lead to deteriorated rubber bushes, seized brake calipers, perished tyre sidewalls, and moisture ingress into fluid systems. Despite the clean MOT record, a prospective buyer should carry out a thorough physical inspection focused on areas that MOT tests do not fully stress-test. Suspension bushes, coil springs, and shock absorbers should be examined for perishing or corrosion, particularly given the car's age and intermittent use. Brake calipers should be checked for binding, and the condition of the brake discs and pads assessed for surface corrosion that can develop during standing periods. The exhaust system and underbody should be inspected for structural corrosion, as the CLK platform of this era can be susceptible to rust in sills, subframes, and jacking points. Tyre age and sidewall condition deserve close attention, as rubber degrades with time regardless of tread depth. The clean MOT history is encouraging, but it should not substitute for a hands-on mechanical inspection. A vehicle that passes its MOT with no advisories is meeting the minimum legal standard, not necessarily confirming long-term reliability. Given the low and sporadic mileage pattern, a pre-purchase inspection by a qualified technician, including a road test and underbody examination, would provide the most reliable assessment of the car's true mechanical condition.
