2014 Mercedes-Benz GL 3.0L Diesel · SN14 OUU

The vehicle presents a high standard of roadworthiness, evidenced by a clean pass in the most recent test on 14 July 2026 at 59,665 miles. The maintenance trend is exceptionally stable, as the car has undergone multiple annual tests without recording any defects or advisories for several years. This consistency suggests a proactive approach to upkeep where the current owner likely addresses potential issues before they escalate into mechanical failures. The mileage profile is notably low for a twelve-year-old vehicle, averaging approximately 5,000 miles per year. The data shows a period of lower use between January 2024 and January 2025, where the vehicle covered only 3,319 miles, followed by a more significant increase in usage between July 2025 and July 2026, where 13,370 miles were clocked in just twelve months. Despite this fluctuation in usage patterns, the total distance remains well below the threshold associated with heavy wear on the drivetrain and engine components, though the low annual mileage can sometimes lead to the hardening of rubber-based components, seals, and the degradation of fluid chemistry during long periods of inactivity. While the MOT history is clean in recent years, the buyer should remain mindful of components affected by low-frequency operation. The records from 2017 and 2019 flagged tyres worn to the legal limit, indicating that previous owners neglected basic consumable replacement until they became critical. Given the age of the Mercedes-Benz GL, a physical inspection should focus on the air suspension system and bushings for cracking or leaking, as these parts perish due to time regardless of mileage. Additionally, check the brake discs for signs of corrosion or pitting, which frequently occur on vehicles that sit stationary for extended periods.
