2015 Toyota Aygo 1.0L Petrol · RO15 BYL

The December 2025 MOT at 67,730 miles resulted in a pass after an initial failure, yet the pattern across three consecutive annual tests reveals a deteriorating maintenance trajectory rather than an improving one. The same suspension bush wear, brake disc degradation, valve stem damage, and sill panel deformation have appeared repeatedly since December 2023, with conditions escalating from "slightly damaged" to "seriously damaged" in the case of all four valve stems. The headlamp cloudiness also progressed from an aim-related failure item in December 2024 to a product-on-lens advisory a year later, indicating superficial attempts at rectification rather than replacement. This is not a vehicle with isolated faults; it carries a cluster of persistent, interconnected wear issues that have been managed through minimal intervention rather than proper repair. Annual mileage accumulation has remained consistent at roughly 2,300 to 3,600 miles per year between tests, with the odometer reading 61,753 miles in December 2023, 65,400 in December 2024, and 67,730 in December 2025. The total recorded figure of 67,730 miles at eleven years old sits at the lower end of average for a 2015 vehicle, suggesting either light urban use or periods of inactivity. Low annual mileage can accelerate corrosion from infrequent use and allow brake discs to degrade without wearing through, which aligns with the pitted and scored front discs noted across all three tests. There are no suspicious mileage discontinuities or clocking indicators in the record. A prospective purchaser should prioritise inspection of the nearside sill panel damage, first flagged in December 2023 and repeated at every subsequent test. While the tester consistently noted that structural rigidity was not significantly reduced, bodywork deformation on an integral structure demands professional assessment for hidden corrosion progression, particularly given the vehicle's age and likely urban parking exposure. The front suspension architecture requires thorough examination: both anti-roll bar bushes, both lower suspension arm rear bushes, and the anti-roll bar linkage pins or bushes have worn across multiple tests, suggesting the entire front end may benefit from refreshed rubber components rather than continued monitoring. The braking system also warrants attention. Front discs have carried advisories for pitting and scoring since December 2024 without yet reaching failure threshold, though the December 2025 test noted they were "not seriously weakened." Combined with the valve stem deterioration pattern, this points to a vehicle that has received reactive, test-driven maintenance rather than preventive care. All four valve stems required replacement at the most recent test. The rear shock absorber misting noted in December 2023 did not reappear in later tests, suggesting it may have been addressed or dried, though the absence of a clean bill on suspension components since 2023 undermines confidence in comprehensive upkeep. Budget for immediate assessment of front suspension bushes, brake disc condition, and professional bodywork evaluation of the sill deformation before committing to purchase.
