2008 Mercedes-Benz CL 500 5.0L Petrol · PK58 ACF

The Mercedes-Benz CL 500 presents a stable roadworthiness record over the past five years, with the most recent MOT in May 2025 at 97,194 miles passing without any defects. This consistency extends back to December 2021, where the vehicle also cleared its test at 88,539 miles with no issues recorded. The only anomaly in the history is the duplicate entry for August 2020, where the car failed a test at 85,845 miles—though no defects were logged, suggesting a possible administrative error rather than a mechanical failure. The absence of advisories or defects in the three subsequent tests indicates that any underlying concerns were either resolved promptly or were non-critical. For a vehicle of this age and mileage, this level of compliance is unusually clean, particularly given the CL 500’s reputation for complex suspension and braking systems. The mileage accumulation is notably low for a car of this vintage, averaging just over 5,400 miles per year since 2020. This suggests either infrequent use or prolonged periods of inactivity, which can contribute to issues like seized components, degraded fluids, or rubber deterioration. The gap between the August 2020 test and the next in December 2021—covering roughly 2,700 miles over 16 months—is particularly striking. Such extended periods of disuse may accelerate wear in non-driving components, such as suspension bushes, coil springs, or brake caliper seals, even if the vehicle passes MOTs. The lack of mileage progression also raises questions about whether the car has been stored rather than actively driven, which could mask latent problems until they become acute. Given the clean MOT history, a buyer should prioritise a thorough inspection of components prone to silent degradation in low-mileage, long-standing vehicles. The suspension—particularly the rear multi-link system—should be checked for worn or hardened bushes, as these can compromise handling and alignment without immediately failing an MOT. Brake system integrity is critical; while no defects were recorded, binding calipers or uneven disc wear could develop over time, especially if the car has been driven infrequently. The exhaust system, including mounts and heat shields, should be examined for corrosion or fatigue cracks, given the CL 500’s tendency for rust in high-stress areas. Finally, fluid levels—brake, coolant, and differential—should be verified, as stagnation can lead to contamination or seal failure. The absence of recorded issues does not eliminate the need for due diligence on these high-risk areas.
