2006 Mitsubishi Colt 1.5L Diesel · GY56 NNC

The 2006 Mitsubishi Colt has demonstrated a stable roadworthiness trend over the past two years, with the most recent MOT test on 9 February 2026 confirming no defects at 66,064 miles. While the January 2025 entry shows a duplicate date—one pass and one fail—this appears to be an administrative anomaly rather than a mechanical issue, as no faults were recorded. The vehicle has passed every test since February 2024 without advisories or major concerns, suggesting consistent compliance with MOT standards. However, the lack of any recorded faults does not preclude hidden wear, particularly in components not routinely inspected such as suspension bushes or drivetrain joints. The recorded mileage of 66,064 miles over 20 years reflects unusually low annual usage, averaging just 3,303 miles per year. This suggests the vehicle has spent extended periods either stored or lightly utilised, which may mitigate some wear-and-tear concerns but could also indicate deferred maintenance. The gap between tests—ranging from 11 to 13 months—is standard, with no abrupt spikes in mileage to suggest aggressive driving or neglect. The consistency in mileage increments implies regular, albeit low-volume, operation rather than high-mileage abuse. Given the absence of MOT-reported faults, a buyer should prioritise a thorough inspection of suspension components, particularly the rear bushes and coil springs, which are prone to fatigue in vehicles of this age. The front and rear brake systems, including calipers and discs, should be checked for uneven wear or binding, especially if the vehicle has been stationary for prolonged periods. Corrosion at wheel arches, subframes, and sills—common in older models—must be assessed for structural integrity, as rust can compromise safety-critical areas. Finally, the exhaust system should be examined for leaks or excessive corrosion, particularly around joints and mounts, as emissions systems in this model are known to degrade over time.
