2005 BMW 740 4.0L Petrol · LM55 AEV

The 2005 BMW 740 presents a notably clean roadworthiness profile, with two consecutive MOT passes and no recorded advisories or defects on either occasion. The most recent test on 6 November 2024 returned a pass with no defects recorded, and this continues the trend established by the prior pass on 8 April 2023. The absence of any advisories over this two-test window means there is no documentary evidence from the MOT history of component wear, corrosion, fluid leaks, or exhaust concerns to draw upon. For a vehicle now over two decades old, this is an unusually tidy record, though it should be noted that MOT testing only samples a limited set of safety and emissions criteria and does not replace a comprehensive pre-purchase mechanical inspection, particularly for a prestige saloon of this age. With 95,427 recorded miles across approximately 21 years of life, this 740 has covered only around 4,544 miles per year, which is exceptionally low even for a luxury vehicle that often sees limited use. The interval between the 2023 and 2024 tests is roughly nineteen months, during which the vehicle would have covered well below 5,000 miles if usage remained consistent. Low annual mileage of this nature carries specific mechanical implications: engine oil, transmission fluid, and coolant can degrade through age rather than service intervals, internal engine seals and gaskets can dry out and weep when the unit runs cold and short journeys dominate, and the six-, eight-, or twelve-cylinder powertrains fitted to this generation of 7 Series can develop oil leaks from the valley pan, valve cover gaskets, and rear main seal when not exercised regularly. Brake discs and calipers are also susceptible to corrosion pitting and binding after prolonged periods of light use, while suspension bushes and ball joints can deteriorate from underloading rather than wear. Given the limited MOT history available, a prospective buyer should commission an independent inspection with particular attention to the areas most commonly affected on E38 and E65 generation 7 Series vehicles at this age. On a test drive, listen for any timing chain rattle from a cold start, as V8 and V12 variants of this era are known for chain guide wear, and observe whether any smoke appears from the exhaust on initial startup that clears as the engine warms. Feel for any hesitation, misfire, or rough idle that could indicate failing ignition coils, a common failure point on the N62 V8. During the road portion of the test, pay close attention to steering response, as the active or hydraulic power steering systems fitted to this model can develop leaks or pump failures that would not necessarily surface during an MOT. Listen for clonks or knocking from the front suspension over uneven surfaces, which would suggest worn control arm bushings or thrust arms, and check for uneven tyre wear on the inside edges that might indicate geometry issues from worn rear trailing arm bushes. Under the vehicle, a thorough inspection of the subframe mounting points, brake pipes, and fuel lines is essential, as corrosion in these areas is a frequent failure mode for 7 Series cars that have seen two decades of UK road salt exposure, even if the most recent MOT did not flag them. Inspect the engine bay and undertrays for any signs of oil seepage from the sump, head gasket, or coolant pipework, and verify that the cooling system has been maintained with fresh coolant rather than neglected during the low-usage period. Check that all electronic systems function correctly, including the iDrive or older navigation interface, climate control, electric seat adjustment, and the operation of all window mechanisms, as electrical gremlins are well documented on this generation. Finally, confirm the service history independently, paying particular attention to whether timing service items, transmission fluid changes, and cooling system refreshes have been carried out at appropriate intervals, as these are the areas most likely to cause costly future repairs on a low-mileage 740 of this vintage regardless of its clean MOT record.
