2021 Mercedes-Benz S 350 L AMG Line Premium + D A 2.9L Diesel · RA21 ABF

The vehicle demonstrates a stable roadworthiness profile, with all three MOT tests from 2024 to 2025 recording no defects. The most recent December 2025 test at 22,631 miles confirmed compliance, indicating consistent maintenance. No recurring issues or escalating faults were flagged across the recorded history, suggesting the previous owner prioritized regular servicing. The absence of advisories or critical failures implies the vehicle has been well-maintained within its low-mileage usage pattern. The mileage progression shows a gradual increase, with 14,840 miles recorded in June 2024, rising to 20,267 by June 2025, and 22,631 by December 2025. This equates to an average annual mileage of 4,526 miles, significantly below the typical 8,000–10,000 miles for a five-year-old vehicle. While this suggests minimal wear on components like tyres and brake pads, it also raises potential concerns about long-term storage or infrequent use. The extended gap between the 2024 and 2025 tests (12 months) and the subsequent 6-month interval may indicate inconsistent servicing, though no issues were detected. A buyer should verify the condition of suspension components, particularly coil springs and bushes, which can degrade if the vehicle remains stationary for prolonged periods. The brake system, including calipers and discs, should be inspected for corrosion or binding, as low mileage may not have sufficiently exercised these parts. Additionally, the exhaust system and structural integrity warrant scrutiny, as stagnant operation can accelerate rust or fluid contamination. The clean MOT history is reassuring, but physical inspection is essential to confirm the vehicle’s actual state beyond recorded data.
