2015 Toyota Aygo 1.0L Petrol · YR15 DXZ

The 2015 Toyota Aygo presents a generally sound mechanical picture, though the most recent MOT on 4 March 2026 at 74,603 miles flagged a notable concern. Both the nearside and offside rear service brakes were recorded as binding, albeit not excessively. This is a new defect compared to the clean bills of health recorded in 2022, 2023, and 2025, suggesting a developing issue rather than a chronic one. The maintenance trend is currently stable but shows a minor downward blip that warrants immediate attention. Left unresolved, binding rear calipers can lead to overheated brake discs, premature pad wear, and uneven braking effort, all of which compromise the vehicle's roadworthiness between tests. The mileage accumulation of roughly 6,782 miles per year is entirely typical for an urban-focused city car of this age. The record shows a steady and consistent climb from 39,568 miles in March 2022 to 74,603 miles by March 2026, with no suspicious gaps or sudden jumps in the odometer reading. This pattern indicates regular use rather than prolonged standing, which is positive for keeping seals, gaskets, and moving components lubricated. The annual test intervals align well with the mileage progression, giving a reliable snapshot of the car's condition at each stage. A buyer should focus their in-person inspection on the rear braking system first and foremost. The binding noted on both rear wheels during the March 2026 test could point to sticking caliper slide pins, a seized handbrake mechanism on one or both sides, or a collapsed flexible brake hose acting as a one-way valve. Have the rear wheels spun freely by a mechanic and check for excessive heat buildup after a short road test. Beyond the brakes, the 2024 advisory on the nearside rear tyre wearing close to the legal limit suggests the rear suspension geometry may need checking, as uneven tyre wear on a beam-axle car often hints at worn bushes or a misaligned axle. Finally, while the MOT record is largely clean and the engine has not triggered any emissions or mechanical failures across five consecutive tests, a thorough underbody inspection is still advisable. Eleven years of urban use in UK road conditions can bring hidden corrosion to subframes, sump pans, and exhaust mounting points, none of which may have reached a failure threshold yet. The Aygo's simplicity is its strength, but neglecting the rear brake issue now could turn a minor fix into a costly repair.
