2010 Toyota IQ 1.0L Petrol · FE60 ACZ

The vehicle remains roadworthy, but the maintenance history shows a concerning trend regarding structural degradation. While the most recent test in January 2026 at 50,228 miles passed, it identified emerging corrosion on the offside and nearside rear inner backing sills. This follows an identical advisory from the January 2025 test at 47,601 miles, indicating that the rust is active and progressing rather than resolving. The transition from a clean record in 2024 to recurring structural issues suggests an accelerating timeline. The mileage profile is exceptionally low for a sixteen-year-old vehicle, averaging approximately 3,139 miles per year. This low usage often preserves mechanical engine components and drivetrain parts, yet it introduces specific risks related to vehicle inactivity. Between December 2021 and January 2023, the car covered only 2,902 miles. This period of low use correlates with the January 2023 advisory where the tester flagged all four tyres for having deep cracks and perished edges. Such patterns indicate that the vehicle likely sits for long periods, causing rubber components to degrade due to age rather than tread wear. A physical inspection must prioritize the structural integrity of the rear chassis. The buyer should specifically examine the inner backing sills to determine if the reported corrosion is surface-level or has caused perforation, which would necessitate expensive welding repairs. Given the low mileage, the braking system should be checked for seized calipers or pitted discs, common in cars that are driven infrequently. Additionally, the age of the tyres and rubber bushings should be verified, as the history proves that the rubber components are prone to dry rotting despite the low mileage.
