1999 Mercedes-Benz CLK 2.0L Petrol · V732 ECC

The vehicle is currently in a failed state following the October 2025 test, showing a significant and rapid deterioration in roadworthiness. While the car maintained a clean record between 2022 and 2023, the most recent inspection at 108,151 miles reveals a widespread array of mechanical and structural failures. The maintenance trend has shifted from stable to worsening, moving from zero defects in 2023 to a comprehensive failure involving lighting, emissions, and critical structural integrity. The recorded mileage of 108,151 over 27 years averages roughly 4,000 miles per year, which is low for a vehicle of this age. This pattern is consistent across the records, showing steady but minimal usage, such as the 4,843-mile increase between the October 2024 and October 2025 tests. Such low annual mileage often correlates with the perishing of rubber components and the onset of corrosion due to infrequent use, a trend supported by the 2021 advisory regarding a cracking nearside rear tyre. A prospective buyer must prioritize a thorough inspection of the chassis and subframe. The October 2025 failure flagged excessive corrosion on the offside rear suspension component mounting area, which significantly reduces the structural strength of the outer sill. This follows previous advisories in October 2024 regarding corrosion on the rear inner suspension mountings and fuel pipes. The presence of corrosion on the nearside and offside front coil springs, along with the offside front lower suspension arm, suggests the vehicle's underside requires urgent attention to prevent further structural degradation. Mechanical concerns extend beyond the chassis. The tester identified an offside front hydraulic leak, a failing wheel bearing with play, and an exhaust emissions failure due to high carbon monoxide levels. The simultaneous failure of the main beam, headlamp aim, and reversing lights indicates a lack of basic electrical upkeep. Any purchase should be contingent on a professional inspection of the fuel system, the integrity of the subframe mountings, and a full diagnostic of the engine's combustion efficiency.
