2005 Daihatsu Sirion 1.3L Petrol · DU05 UXA

The Daihatsu Sirion’s MOT history presents a stable but irregular pattern of roadworthiness, with the most recent test in October 2023 at 102,762 miles passing without any defects. The absence of advisories or failures in the latest record suggests the vehicle met all DVSA thresholds for structural integrity, emissions, and critical mechanical components at that point. However, the two consecutive failures in October 2021—both at around 91,327–91,340 miles—indicate a brief period of non-compliance, though the exact reasons remain unspecified in the provided data. Given the lack of recurring advisories or defects across the four recorded tests, there is no clear trend of worsening mechanical issues, but the irregular testing intervals (some tests just days apart, others spanning nearly two years) raise questions about consistent upkeep. The Sirion’s mileage of 102,762 over 21 years equates to roughly 4,893 miles annually, which is unusually low for a vehicle of this age. This suggests either infrequent use or prolonged periods of inactivity, both of which can contribute to issues like seized components, degraded fluids, or corrosion. The rapid accumulation of just 5,248 miles between the October 2021 failures and the October 2022 tests—followed by another 6,168-mile gap before the 2023 pass—further implies sporadic maintenance or ownership changes. Without advisories on fluid levels, battery condition, or tyre wear in the MOT records, a buyer cannot rule out deferred maintenance on non-critical systems. Given the clean MOT history, a prospective purchaser should prioritise a thorough inspection of components prone to neglect in low-mileage vehicles. Pay particular attention to the suspension—check for degraded bushes, worn coil springs, or signs of binding in the steering or suspension mounts, as these can stiffen over time even with minimal use. The brakes should be tested for uneven wear, seized calipers, or corrosion on discs and pads, especially if the vehicle has sat unused for extended periods. Structural corrosion, particularly around wheel arches, sills, and the underbody, is another key concern, as moisture ingress during inactivity accelerates rust. Finally, verify fluid conditions—power steering, brake, and coolant levels—along with the battery’s health, as these are often overlooked in vehicles not driven regularly. While the MOT record offers reassurance on major defects, the irregular testing and low mileage history demand caution. The absence of advisories does not guarantee the vehicle has been meticulously maintained, so a pre-purchase inspection by a qualified mechanic is strongly advised to confirm the absence of hidden issues.
