2017 Mercedes-Benz SL 4.7L Petrol · NS55 MOG

The vehicle presents a high level of roadworthiness with a stable maintenance history across the last four years. The most recent test on 20 June 2025 at 32,360 miles passed with no defects recorded, following a technical failure just three days prior at 32,292 miles. Because the failure record lists no specific defects, this suggests a potential administrative or tester error or a minor issue that was rectified immediately before the retest, rather than a systemic mechanical failure. The mileage pattern is exceptionally low for a nine-year-old vehicle, averaging approximately 3,600 miles per annum. Between October 2022 and October 2023, the car covered only 3,002 miles, indicating long periods of stationary time. The jump of 7,679 miles recorded between June 2024 and June 2025 represents a slight increase in usage but remains well within low-use parameters. While this low mileage suggests minimal wear on the drivetrain and engine components, it often increases the risk of age-related degradation in rubber seals, fluid acidity, and tyre rot. A buyer should focus their physical inspection on components affected by low-mileage storage. Check the brake discs for surface pitting and seized calipers, as infrequent use often leads to corrosion and binding. Inspect the suspension bushes and split boots for cracking or dry rot, as these materials perish over time regardless of the distance driven. Given the clean MOT history regarding structural integrity, the primary concerns remain the condition of consumables and the state of fluids that may have sat stagnant during the extended intervals between tests.
