2010 Toyota IQ 1.0L Petrol · B8 DNN

Structural corrosion and suspension wear identified during the 2023 inspection define the primary mechanical narrative for this vehicle, despite a return to clean test passes in 2025 and 2026. The shift from a clean record in 2022 to multiple advisories regarding chassis corrosion and suspension bush degradation in 2023 suggests a period where environmental exposure began to impact the vehicle's structural integrity. While the most recent MOT on 13 July 2026 resulted in a pass with no recorded defects, the presence of these historical advisories necessitates a focused physical inspection of the underbody to ensure that the previously noted corrosion has not progressed beneath the surface or been masked by superficial treatments. Accumulating approximately 81,072 miles over sixteen years results in an average annual usage of roughly 5,067 miles, a figure that is relatively low for a vehicle of this age. This usage profile indicates that the car has not been subjected to the high-mileage motorway cycles that typically accelerate drivetrain fatigue, though it does increase the likelihood of short-trip cycles. Such patterns can lead to increased condensation within the exhaust system and potential premature wear on brake components due to lack of regular, high-heat usage. Prospective buyers should note that the consistent testing intervals indicate the vehicle has remained in active service, avoiding the extended periods of inactivity that often cause internal engine component degradation or seized mechanical linkages. When evaluating the vehicle on a test drive, specific attention must be paid to the suspension components flagged in 2023, particularly the front suspension arm bushes. Listen carefully for metallic knocks, clunks, or clicking sounds when navigating uneven road surfaces, speed bumps, or tight cornering maneuvers, as these are primary indicators of worn or cracked rubber bushings. Any vagueness in the steering or a tendency for the vehicle to pull to one side during braking or acceleration may point to the residual effects of the previously noted suspension wear. Furthermore, verify that the steering remains precise and that there is no excessive play in the wheel assembly when the vehicle is stationary. A thorough physical examination of the chassis mounting points is essential to confirm that the corrosion noted in 2023 has not advanced. Use a torch to inspect the areas around the front strut mountings and the rear structural members for signs of flaking rust or compromised metal integrity. While the current clear MOT status indicates that these areas met the required standards at the time of the last inspection, the history of corrosion warrants a proactive check for any signs of structural weakness or ongoing oxidation. Ensure that the brake pedal feel is firm and consistent, as the 2020 advisories regarding thin brake pads serve as a reminder that the braking system, while currently functional, remains a high-wear area that requires periodic monitoring based on the vehicle's specific usage patterns.
