2021 Peugeot 308 1.5L Diesel · KN21 ASO

The 2021 Peugeot 308 has demonstrated consistent roadworthiness in its most recent MOT on 2026-03-13 at 165,306 miles, with no defects recorded. The prior tests in 2025-02-19 (136,350 miles) and 2024-03-15 (106,825 miles) also passed without issues, indicating a stable maintenance trend. No advisories or critical failures were noted across the three consecutive assessments, suggesting the vehicle has been maintained to meet legal standards. However, the absence of recorded defects does not preclude hidden wear, particularly given the high mileage relative to its age. The vehicle’s mileage progression reveals a steady accumulation of 29,525 miles between 2024 and 2025, followed by 28,956 miles in the subsequent year. This equates to an average of 33,061 miles annually, exceeding typical usage for a five-year-old vehicle. Such rapid mileage may accelerate wear on components like suspension bushes, coil springs, and brake discs, though no evidence of this appears in the MOT records. The lack of gaps in testing suggests regular compliance, but the high usage rate warrants scrutiny of mechanical integrity beyond basic emissions and lighting checks. A buyer should prioritise inspecting the suspension system for excessive play or worn bushings, which could manifest as uneven tyre wear or handling instability. Brake discs and calipers should be checked for warping or corrosion, as high mileage often exacerbates these issues. Additionally, the exhaust system and underbody should be examined for rust, as the vehicle’s age and mileage increase vulnerability to corrosion. While the MOT history shows no immediate risks, the combination of high annual mileage and the absence of detailed mechanical reports necessitates a thorough pre-purchase inspection to confirm long-term reliability.
