2015 MG 3 1.5L Petrol · GJ15 ADZ

The 2015 MG 3 demonstrates a stable roadworthiness trend, with no defects recorded in its last three MOT tests, including the most recent 2025-09-05 assessment at 79,753 miles. The vehicle passed all checks without issues, suggesting consistent maintenance. However, a failed test on 2022-04-05 at 55,283 miles—despite no defects being noted—raises questions about potential procedural or minor technical oversights. The absence of recurring faults in subsequent tests implies no systemic deterioration, but the gap between the 2022 failure and the 2023-09-07 pass at 63,598 miles warrants scrutiny. The vehicle’s mileage of 79,753 miles over 11 years aligns with an average of 7,250 miles annually, reflecting typical usage. Notably, the 2022-04-05 test recorded 55,283 miles, followed by a 8,315-mile increase to 63,598 miles by 2023-09-07, indicating a period of higher-than-average usage. This spike could accelerate wear on components like suspension bushes, coil springs, or brake discs. The lack of defects in later tests suggests these elements were addressed or remained functional, but the absence of detailed records for the 2022 failure limits definitive conclusions. A buyer should prioritise inspecting the exhaust system for corrosion, given the vehicle’s age, and check for binding calipers or uneven brake disc wear, which may not always trigger MOT failures. Suspension components, particularly rear bushes and coil springs, should be evaluated for fatigue, as gradual wear could manifest without immediate fault codes. The absence of structural rust or major mechanical issues in the MOT history is reassuring, but physical inspection is critical to confirm the integrity of high-mileage parts and address any unresolved concerns from the 2022 test.
