1986 BMW 635 3.4L Petrol · HIA 236

The vehicle is currently roadworthy, having passed its most recent MOT in May 2023 with 125,070 miles and no recorded defects. The maintenance trend shows an improving trajectory following a period of recurring mechanical issues between 2018 and 2021. While earlier tests highlighted multiple suspension and fluid leak concerns, the clean sheet from the 2023 test suggests that the current owner has addressed the pressing mechanical faults identified in previous inspections. The mileage profile is exceptionally low for a forty-year-old vehicle, averaging approximately 3,127 miles per year. Between December 2021 and May 2023, the car covered only 1,286 miles, indicating infrequent use or long periods of storage. This low usage typically reduces wear on the drivetrain and engine components but often accelerates the degradation of rubber-based parts and encourages corrosion on fluid lines. The consistent low-increment between annual tests suggests the car is used as a seasonal or enthusiast vehicle rather than a daily driver. A buyer must conduct a thorough physical inspection of the chassis and jacking points, as the 2021 test flagged corrosion within 30cm of a mounting on all four corners. Although this did not affect security at that time, structural rust on older BMWs is prone to rapid progression if left untreated. The inspector should also verify the brake pipe condition, as the 2021 record noted corroded pipes running from the rear to the front, which is a common failure point on this model. The suspension and steering systems require close scrutiny. The history shows a pattern of nearside shock absorber failure, steering box seepage, and worn anti-roll bar bushes between 2018 and 2021. While these appear to have been rectified, the buyer should check for new oil leaks at the steering rack and ensure the rear brake discs, which were noted as pitted and scored in late 2021, have been replaced and are not resurfaced.
