1986 BMW 6 Series 3.5L Petrol · D500 HKR

The vehicle is currently roadworthy but the maintenance trend shows a concerning shift toward structural and suspension degradation. While the most recent test in August 2025 at 182,368 miles passed, it identified severely deteriorated dust covers on both the nearside front anti-roll bar and offside front lower suspension arm. This follows a significant failure in July 2024 where the chassis was rejected due to major corrosion on the offside front suspension mounting area. The transition from a clean record in 2023 to structural failures suggests that the metal integrity is now actively failing. The recorded mileage of 182,368 miles over forty years represents a low annual average rate of approximately 4,500 miles. However, the data reveals extreme inconsistency in use between 2022 and 2025, where the vehicle covered only 72 miles in three years. This pattern suggests the car sits for long periods, which often leads to the accelerated perish of rubber components, such as boots and seals, alongside the development of corrosion. The lack of regular movement explains the deterioration of suspension joints and mounting points despite the low mechanical wear. A buyer must conduct a thorough physical inspection of the underside to verify the repairs made to the offside front suspension mounting. The 2024 failure for structural corrosion in a prescribed area is a critical red flag that requires professional welding rather than simple surface treatment. Attention is also required for the nearside rear wheel arch, which was flagged for corrosion in two consecutive tests, ensuring the rust has not progressed into the inner sills. The oil leak noted in 2022 should be monitored to ensure it has not worsened into a significant leak during the periods of inactivity.
