Structural integrity and chassis corrosion represent the primary mechanical risks for this vehicle, following a failed test in March 2025 regarding excessive corrosion to a nearside front suspension component mounting on the outer sill. While the most recent test on 18 April 2026 resulted in a pass, it introduced new advisories for corrosion on both the nearside and offside rear vehicle structures or chassis within 30cm of a mounting. This pattern indicates an ongoing progression of oxidation on the structural sills and mounting points, which has moved from a major failure point in 2025 to a persistent advisory status in 2026. The recorded mileage of 114,906 miles over a 35-year lifespan equates to a low annual average of approximately 3,283 miles. This usage pattern is significantly below the typical UK average for a vehicle of this age, suggesting the car has spent considerable periods stationary or has been used only for infrequent, short-distance trips. Mechanically, such low annual accumulation can often correlate with the development of surface corrosion on the underside, as evidenced by the 2024 advisories noting the underside, suspension, and braking components were covered in surface corrosion. Prospective buyers should pay close attention to the chassis and sills during a physical inspection, specifically looking for bubbling paint or flaky metal around the mounting points identified in the 2025 and 2026 tests. On a test drive, any irregular knocking or creaking sounds when traversing uneven surfaces or bumps could indicate that the structural corrosion is beginning to affect the rigidity of the suspension mounting areas. Additionally, the steering system should be monitored closely for any play or wandering, given the previous major failure regarding a missing nearside steering rack gaiter. The braking system also requires scrutiny due to the 2024 advisories regarding corrosion on the brake hose ferrules. While no direct failures were recorded for the braking system in the latest test, the history of surface corrosion on braking components warrants a careful check for any signs of fluid weeping or stiffness in the pedal feel. A sudden change in pedal pressure or a pulling sensation under braking could indicate that the previously noted corrosion is impacting the integrity of the brake lines or the performance of the calipers.
