2006 Peugeot 107 1.0L Petrol · SH06 SEO

A clear pattern of progressive structural and suspension corrosion defines the mechanical outlook for this 2006 Peugeot 107, despite the vehicle continuing to pass its annual roadworthiness examinations. The November 2025 test passed with advisories specifically noting front coil spring corrosion, corroded strut mounting areas, and worn anti-roll bar and lower arm bushes, representing a migration of deterioration that was previously concentrated at the rear axle onto the front. Of greater concern, the October 2023 test resulted in a failure due to an excessively corroded nearside rear outer sill that was holed within the axle forward mounting prescribed area, significantly reducing load-bearing integrity. While the car subsequently passed in November 2023 after the sill was presumably repaired, advisories from the same test recorded severe corrosion on both rear coil springs and surface corrosion throughout the entire rear body structure concentrated around the inner sills and axle mountings. The progression from a 2022 pass with only minor consumable wear to repeated structural advisories and a major failure item within twelve months demonstrates a worsening corrosion profile rather than a stable condition. Recorded mileage of 74,143 miles over a twenty-year lifespan equates to an annual accumulation of approximately 3,700 miles, which is notably low for the vehicle's age. This restrained usage figure suggests either a vehicle used primarily for short urban journeys or extended periods of inactivity. Mechanically, such low annual mileage does not materially reduce corrosion risk because environmental exposure, road salt, and moisture continue to act upon the body structure and undercarriage regardless of mileage accrued. The MOT record reflects consistent annual testing without significant gaps, indicating the vehicle has remained in active use throughout its life rather than being laid up, and the mileage progression between tests appears broadly consistent with the stated annual rate. For a prospective buyer, the rear body corrosion and suspension condition warrant close physical inspection rather than reliance on the pass certificate alone. Examine both rear inner sills, the outer sill around the nearside rear axle mounting, and the rear floor pan for any evidence of previous welding, filler, or bubbling that could indicate concealed structural weakness. Inspect both rear coil springs for active flaking or cracking at the upper and lower rubber seats, and check the front strut top mounts for any looseness or visible corrosion weeping through the turret area. On test drive, listen for clonking or knocking from the rear over uneven surfaces, which could indicate deteriorated rear axle mountings, and pay attention to any knocking from the front suspension, particularly over speed humps, which may suggest the worn anti-roll bar linkage and lower arm bushes have progressed beyond advisory thresholds. Additionally, check for signs of exhaust gases at the manifold area, as a minor leak was noted in 2023, and verify headlamp lens condition, given the previous major failure for outer lens deterioration on the nearside side. The remaining advisories from the 2022 test around thin front brake pads and perished tyres are routine consumable items expected on a vehicle of this age and should be budgeted for as standard replacement. Given the documented history of structural corrosion advisories and a recent failure related to sill integrity, any prospective purchase should be accompanied by a hands-on underbody examination, ideally on a ramp, to confirm the current condition of the repaired sill area and assess whether the corrosion pattern has continued to advance since the most recent test in November 2025.
