2004 Mercedes-Benz CL 500 5.0L Petrol · M500 AAJ

This Mercedes-Benz CL 500 presents a stable and clean MOT history over the past three and a half years, with the most recent test on 21 January 2026 at 87,081 miles showing no defects or advisories. The consistent passing record—spanning from September 2022 (78,982 miles) through to the latest—indicates that major mechanical components, including brakes, suspension, steering, and structural integrity, have been maintained to DVSA standards. The absence of recurring advisories or failures suggests that routine servicing has been prioritised, particularly in areas prone to wear such as brake systems, exhaust emissions, and lighting. That said, the near-three-year gap between the September 2022 and January 2023 tests is unusual for a vehicle of this age, though it did not result in any outstanding issues upon retesting. The car’s mileage accumulation— 87,081 miles over 22 years , averaging just 3,958 miles annually —is exceptionally low, even for a luxury vehicle. This suggests either infrequent use, prolonged periods of inactivity, or a combination of both. The 2,951-mile jump between January 2025 (84,790 miles) and January 2026 (87,081 miles) contrasts with the slower 1,151-mile increase between September 2022 (78,982 miles) and January 2023 (79,666 miles) , hinting at phases of either storage or very light driving. While low mileage typically reduces wear on consumables, it can also mask hidden issues—particularly in fluid systems (brake, coolant, power steering) or rubber components (suspension bushes, seals) that degrade over time regardless of usage. The lack of recorded advisories does not eliminate the need for a pre-purchase inspection of these areas. For a prospective buyer, the primary focus should be on components less frequently scrutinised in MOT tests but critical for long-term reliability. Given the vehicle’s age and low mileage, inspect the suspension geometry and bushings —particularly the rear coil springs and anti-roll bar links—for signs of hardening or corrosion, as these can compromise handling. Check the brake system thoroughly , including the condition of calipers, brake discs, and hydraulic lines , as binding or uneven wear could have gone unnoticed without dynamic testing. The exhaust system should be examined for rust or leaks, especially around the manifold and catalytic converter, given the car’s age. Finally, verify the fluid levels and condition —brake fluid, engine oil, and differential lubricants—since stagnation can accelerate degradation. While the MOT history is reassuring, a pre-purchase inspection by a Mercedes-Benz specialist would be prudent to confirm the absence of latent issues in a vehicle that has clearly seen limited use.
