2020 Mercedes-Benz SLC 300 Final Edition Prem A 2.0L Petrol · SL 1128

The Mercedes-Benz SLC 300 Final Edition Prem A presents a clean MOT history over its recent testing cycle, with the most recent inspection on 3 March 2026 at 26,611 miles showing no defects—an outcome mirrored in the three preceding tests from 2025 and 2024 . The vehicle’s maintenance trend appears stable, with no advisories or failures recorded in the past two years, suggesting that routine checks and servicing have been addressed promptly. The only anomaly is the 2024 February double-entry , where the same mileage (20,910) appears once as a pass and once as a fail with no defects noted—a clerical irregularity rather than a mechanical issue. This consistency in passing, combined with the absence of recurring advisories, indicates that the car has been well maintained under its current ownership, at least in terms of compliance with MOT standards. The vehicle’s mileage of 26,611 miles over six years —roughly 4,435 miles annually —is exceptionally low for its age, falling well below the UK average for a six-year-old car. This suggests either infrequent use, extended periods of inactivity, or potentially a secondary vehicle status. The gap between the 2023 February test at 15,287 miles and the 2024 February test at 20,910 miles (a 5,623-mile jump in 12 months ) contrasts with the slower accumulation in earlier years, hinting at a possible shift in usage patterns. Without further service records, it’s impossible to confirm whether this low mileage has spared the car from typical wear, but it does raise questions about whether components like suspension bushes, brake fluid, or battery health have been neglected during periods of disuse. Given the absence of defects in the MOT history, a prospective buyer should still conduct a thorough pre-purchase inspection, focusing on areas prone to hidden wear despite low mileage. Pay particular attention to brake system integrity , including the condition of disc pads, calipers, and hydraulic lines , as binding or seized brakes can occur even with minimal use due to fluid degradation or corrosion. Check suspension components —such as coil springs, dampers, and bushings—for signs of drying out or corrosion, especially if the car has spent extended periods stationary. Exhaust emissions systems should also be verified, as modern diesel or petrol systems can develop faults without high mileage if fluid changes have been overlooked. Finally, inspect for structural corrosion in high-stress areas like wheel arches, sills, and underbody panels, as moisture retention in a low-mileage vehicle can accelerate rust formation. The clean MOT record is a positive sign, but these targeted checks will confirm whether the car’s low usage has translated into genuine preservation.
