2006 Toyota Prius 1.5L Other · GY06 BOU

The Prius holds a valid MOT pass dated 4 September 2025 at 187,593 miles, yet the maintenance trend is clearly worsening. That same day, a failed test preceded the pass, revealing a catalogue of corrosion and wear items that the tester deemed serious enough to fail the vehicle initially. The pass was achieved only after rectification, but the sheer volume of advisories and defects recorded at the most recent test raises serious questions about the car's long-term structural integrity and upkeep. Mileage accumulation sits at roughly 9,380 miles per year over twenty years, which is typical for its age. The record shows a gap of almost exactly one year between the August 2024 and September 2025 tests, with just 2,256 miles added in that period, suggesting lighter recent use or possibly a period of limited driving. No glaring mileage anomalies or suspicious jumps appear in the data provided, though the sparse testing history, with only three test events logged since 2023, limits how confidently one can assess the wear trajectory. The most pressing concern is corrosion. The September 2025 failure flagged underbody corrosion and chassis corrosion within 30cm of mounting points on all four inner and outer sills, along with a corroded front sub-frame and corroded front coil springs. While the tester noted these did not seriously affect overall security at the time of the pass, corrosion on structural mounting points and suspension springs on a twenty-year-old vehicle can deteriorate rapidly and may compromise structural integrity if left unaddressed. A buyer should have the sills, sub-frame, and spring mounting points inspected in person with a thorough underside examination, ideally on a ramp. Beyond the structural concerns, recurring mechanical issues demand attention. The offside front outer CV joint boot has appeared as severely deteriorated in both the 2024 and 2025 tests, suggesting either a temporary repair or ongoing neglect. The offside front anti-roll bar ball joint was excessively worn at the 2025 failure, and both front and rear brake discs have been flagged as worn, pitted, or scored across multiple tests. Tyre condition advisories on the nearside front and rear also appeared in 2025, indicating perishing or cracking. A buyer should verify whether the CV boot has been replaced, check the anti-roll bar linkage for play, and assess the condition of all brake discs and tyres before committing to purchase.
