2006 Land Rover Range Rover 3.6L Diesel · HN56 PVL

The vehicle is currently roadworthy, but the maintenance trend shows a concerning decline regarding structural integrity. While it passed the most recent test in August 2025 at 132,187 miles, this followed a failure due to significant underbody corrosion affecting the floor and the rear subframe. The transition from a surface corrosion advisory in 2024 to a failure requiring underbody undersealing in 2025 indicates that the rust is active and progressing rather than remaining stable. The mileage pattern is consistent with a vehicle of this age, averaging approximately 6,600 miles per year. Between August 2022 and August 2025, the vehicle covered 7,735 miles, representing a steady and low-usage profile. This low mileage suggests that the drivetrain and engine may have less mechanical wear, but it also correlates with longer periods of exposure to the elements while sitting stationary. The gap between annual tests suggests a regular routine of testing, yet the low annual mileage does not offset the underlying physical degradation of the chassis. A buyer must conduct a thorough physical inspection of the rear subframe and floor pans to determine if the corrosion has reached a point of structural weakness. The 2025 record notes that the underbody was undersealed to address the corrosion, which often masks existing rust rather than curing the metal entirely. Particular attention should be paid to the condition of the brake pipes, as these were specifically mentioned during the undersealing process. Given the history of structural rust, the integrity of the suspension mounting points and exhaust hangers remains the primary risk to the long-term viability of this Range Rover.
