Faults:

Excessive oil consumption. This is due to worn valve guide seals, allowing oil to leak into the combustion chamber.

Injector failures.

High-pressure fuel pumps (HPFPs) are prone to failure, resulting in a sudden loss of power and causing the engine to go into limp mode.

The wiring and crankshaft or camshaft position sensors can fail due to the extreme heat generated by the V8 engine.

General Comments:

Driving this car is truly a dream.

You barely feel a thing when you're on the highway at over 150 km/h, which is where I particularly enjoy driving it. The acceleration is powerful, and it's excellent for overtaking.

The twin-turbo engine is captivating, both for its sound and its power, but it's prone to oil leaks, so it requires an impeccable service history. With rigorous maintenance, the car runs like a dream.

The 4.4-liter V8 engine delivers 400 horsepower, and the all-wheel drive (xDrive) provides excellent grip in various weather conditions. It does consume a fair amount of fuel, though, averaging just over 11 liters per 100 kilometers. If you like to put your foot down, fuel consumption will obviously increase, and this car certainly encourages you to do so.

As for interior comfort, as expected from BMW, it's superb. It stands out for its top-of-the-line cabin, spacious seats, and luxurious amenities, ideal for long journeys, although the steering feel can sometimes feel artificial or too light.

Maintenance is the most critical aspect of the car. The N63 engine requires rigorous maintenance, and annual repair costs can easily exceed the average for its class due to common problems such as turbocharger wear or failures in the electrical and cooling systems.

I can't say it's a cheap car, but if you take good care of it, it's as reliable as an old-school model. It's worth the price; driving it is a truly enjoyable experience, especially if you use it daily like I do.

It's a car for enthusiasts; anyone who owns one knows what to expect. In my case, it's perfectly maintained, and everything works like it did the day I got it.

Faults:

- GPS stopped working.

- Stereo sound muted when turning left (!)

- Engine started running uneven and misfiring, £4000 later and the problem was fixed.

General Comments:

I love the design of the old E38 7-series and I was really out to get a 740 V8, but this 750 V12 looked stunning with its low mileage and well documented history in Monaco. The car seemed perfect on the outside...

I have a good friend who has gone through 3 of these V12s and never had a problem, but my car seemed to have every annoying little fault possible. When it worked, for the first few months it was truly astonishing, performance, acceleration and comfort was top class and I still love the clean look of a standard, well kept E38. When things started going wrong, it was not so fun anymore. Settle for a 740 and you probably have one of the best cars ever, the 750 is for the few who appreciate, and can afford the refinement of a V12.

What is interesting is that I got the same long-distance mileage on the 750 as on my current 530.
