The vehicle remains currently roadworthy, though the most recent inspection indicates the onset of wear in the front suspension. While it passed the May 2026 test at 75,126 miles, the tester flagged light misting of oil on both the nearside and offside front shock absorbers. This represents a shift from the clean records seen in 2024 and 2025, suggesting that the suspension components are beginning to degrade due to high mileage demands. The mileage pattern reflects high annual usage for a five-year-old vehicle, averaging approximately 15,000 miles per annum. There is a significant jump in distance between the April 2024 test at 40,829 miles and the May 2025 test at 59,808 miles, showing an increase of 19,000 miles in just thirteen months. This rapid accumulation puts consistent strain on heavy-duty components such as the drivetrain, braking system, and bushings compared to lower-average examples. A prospective buyer should conduct a thorough physical inspection of the front suspension to determine if the misting has progressed to a functional leak that requires immediate replacement. Given the high mileage, the inspection should also target the condition of the brake pads and discs and the integrity of the rubber bushings, as these often show accelerated wear under these conditions. While the history shows no structural defects, the shock absorber advisory indicates the vehicle is entering a phase requiring more frequent mechanical maintenance.
