2017 BMW 730 3.0L Diesel · FT 1000

The latest MOT test conducted on 4 July 2025 resulted in a pass with no defects recorded. The overall maintenance trend for this vehicle is exceptionally stable, as the history shows a consistent pattern of passes without any recorded advisories over several years. While a failure was noted on 17 July 2024, the vehicle was retested and passed just two days later, suggesting a minor or clerical issue that was immediately rectified. The absence of recurring defects indicates a vehicle that has been maintained to a high standard. The recorded mileage of 43,682 miles over approximately nine years is significantly lower than average for a luxury saloon of this age, averaging roughly 4,854 miles per year. While this suggests minimal wear on the internal engine components and the drivetrain, such low usage often indicates that the vehicle has spent extended periods stationary. This usage profile shifts the mechanical risk from wear-and-tear degradation to time-based deterioration, which requires a specific approach during the pre-purchase inspection. Given the clean MOT record and low mileage, the buyer should focus on components that degrade regardless of distance traveled. A thorough inspection of the tyre sidewalls is essential to check for perishing or hairline cracking, as rubber compounds harden and lose grip over time even if the tread remains deep. The braking system should be scrutinized for heavy surface corrosion on the brake discs and the potential for binding calipers, both of which are common symptoms of a vehicle that has stood for long periods without regular use. Additionally, the health of the 12V battery should be verified using a diagnostic tool, as the high electronic load of a BMW 7 Series can quickly deplete a battery that is not regularly charged through frequent driving. It is critical to verify the service book stamps to ensure that engine oil and other vital fluids have been replaced according to calendar intervals rather than mileage alone, as fluid degradation occurs over time. Finally, the buyer should inspect the suspension bushes for signs of drying or cracking and ensure there is no evidence of standing corrosion on the underbody.
