The vehicle is currently roadworthy, but the maintenance trend shows a recent period of neglect regarding basic safety consumables. While the most recent test in October 2025 at 31,922 miles passed, it followed a cluster of three failures within a two-month window. This sequence indicates a reactive maintenance approach where faults were only addressed once the vehicle failed legal inspections, rather than through preventative upkeep typical of high-end executive machinery. The mileage profile is notably low for a six-year-old vehicle, averaging approximately 5,320 miles per annum. However, there is a significant gap in activity between September 2024 at 25,441 miles and September 2025, where the car covered only 6,165 miles in a year. This low-frequency usage suggests the vehicle may have sat stationary for extended periods, which can lead to rubber degradation, flat-spotting of tyres, and seizing of various mechanical components despite the low distance travelled. A prospective buyer must conduct a thorough physical inspection of the tyres and artwork alignment. The MOT history reveals multiple failures for cuts, exposed cords, and uneven wear across all axles, which suggests either poor tyre quality, incorrect suspension geometry, or a failure to monitor tyre health. Given the recurring "worn on edge" defects, the suspension bushes and control arms should be checked for excessive play to ensure that the low mileage has not masked underlying mechanical issues caused by prolonged standing.
