2026 MG S9 Premium Phev Auto 1.5L Hybrid electric · DO08 YLE

The vehicle presents a stable roadworthiness profile following its most recent inspection. The MOT test conducted on 27 October 2025 at 139,342 miles resulted in a pass with no defects recorded, indicating that the primary mechanical and safety systems currently meet the minimum standard. This follows a brief failure in October 2024 which was rectified quickly within twenty-four hours, suggesting that any identified issues were addressed immediately rather than being allowed to persist. The mileage accumulation is exceptionally high for a vehicle of this age, reflecting heavy long-distance usage. Between October October 2022 at 106,223 miles and October 2025 at 139,342 miles, the car covered 33,119 miles in just three years. This averages to over 11,000 miles per annum, significantly exceeding the typical UK consumer average. While the MOT record remains clean of structural advisories, the rate of travel puts significant strain on wear components, particularly the suspension geometry, braking system, and the hybrid powertrain cooling systems. A buyer should focus their physical inspection on the high-wear areas associated with such high mileage figures. Given the 139,342-mile mark, check the condition of the suspension bushes, control arms, and shock absorbers for signs of premature fatigue. The brake discs should be inspected for thinning or uneven scoring, as high-frequency use often accelerates hardware degradation. Because the vehicle is a PHEV, verify the service history includes specific high-voltage system-battery checks to ensure the high mileage has not resulted in neglected electrical maintenance.
