2012 BMW 6403.0L Diesel

The BMW 640 presents a clean and stable MOT history, with the most recent test on 10 April 2026 at 131,646 miles showing no defects or advisories. This consistency extends back through the three preceding annual tests—2025 (124,428 miles), 2024 (117,040 miles), and 2023 (114,847 miles)—all of which also passed without issues. The only deviation is the September 2022 test at 95,323 miles, which similarly passed but reflects a notable 19,524-mile gap until the October 2023 test, suggesting either infrequent use or a delay in testing. The absence of recurring advisories or defects in the past four years indicates that major mechanical components—such as brakes, suspension, steering, and structural integrity—have been maintained at a high standard, or any latent issues have been preemptively addressed. The vehicle’s mileage accumulation aligns closely with typical expectations for its age, averaging around 9,403 miles per year over its 14-year lifespan. The most recent 12-month period (April 2025–April 2026) saw 7,218 miles logged, which is modest but not unusual for a luxury vehicle, particularly if used primarily for urban or occasional long-distance travel. The gap between September 2022 (95,323 miles) and October 2023 (114,847 miles) marks a 19-month period with 19,524 miles covered, suggesting either a period of reduced use or a deliberate deferral of the MOT test. This pattern does not raise red flags for wear, but it does imply that the car may have spent extended periods in storage or seen limited daily driving. Given the absence of defects in the MOT record, a buyer should still conduct a thorough pre-purchase inspection, focusing on components not routinely checked in standard MOT tests. Pay particular attention to the suspension—specifically the condition of coil springs, anti-roll bars, and bushings—since these are not always scrutinised unless visibly worn or damaged. The brake system, including calipers, pads, and discs, should be checked for uneven wear or corrosion, even though the MOT history shows no issues. Exhaust emissions and the integrity of the exhaust system should also be verified, as these are not always flagged unless there’s a clear failure. Finally, inspect the underbody and wheel arches for signs of corrosion or structural weakening, particularly in a 14-year-old vehicle exposed to UK road conditions. While the MOT record is reassuring, these areas often reveal hidden maintenance neglect.
