BMW 7302017 · 3.0L Diesel

The 2017 BMW 730 has demonstrated consistent roadworthiness across all five MOT tests, with no defects or advisories recorded since its last inspection on 19 May 2025 at 48,910 miles. This clean history suggests the vehicle has either undergone regular professional servicing or benefited from careful owner maintenance, as no recurring issues have emerged to warrant test failures. The most recent MOT, just over a year ago, confirms the car remains compliant with current UK standards for emissions, brakes, suspension, and structural integrity. However, the absence of advisories does not preclude underlying wear—particularly in high-mileage components like suspension bushes, coil springs, or brake calipers—which may now require closer scrutiny. The recorded mileage of 48,910 miles over nine years equates to an average of approximately 5,434 miles annually, a figure significantly lower than the UK average for a vehicle of this age. This suggests the car has either been used sparingly or stood unused for extended periods, which could impact fluid degradation, tyre condition, and minor wear items such as wiper blades or battery health. Notably, there is a gap of around 18 months between the 2021 and 2022 MOTs, during which the mileage increased by just 5,991 miles—a slow accumulation that may indicate limited usage. Conversely, the jump from 37,385 to 44,593 miles between 2022 and 2023 (7,208 miles in a year) is the most rapid, though still modest. This pattern implies the vehicle has not been subjected to aggressive driving conditions, but it also raises questions about whether critical fluids (e.g., brake fluid, coolant, differential oil) have been refreshed according to manufacturer intervals. Given the clean MOT history, a prospective buyer should prioritise an independent inspection of suspension components, particularly the rear bushes and coil springs, which are prone to fatigue over time. The lack of advisories does not guarantee these have not degraded, especially if the car has been stationary for prolonged periods, leading to rubber perishing or metal fatigue. Brake discs and calipers should also be examined for uneven wear or binding, as these are not always captured in MOT tests unless they fail to meet minimum thickness or functionality standards. Additionally, the battery, which may have been overlooked in low-mileage usage, should be tested for capacity and corrosion at terminals. Finally, a thorough check of the underbody for corrosion—particularly around the sills, subframe, and exhaust system—is essential, as rust can compromise structural integrity without immediately affecting MOT passability.
