BMW 750i 4.4L V8 Petrol (2017) - 450 BHP For sale: my 2017 BMW 750i 4.4L V8 Petrol (450 BHP) in excellent condition. The car looks and drives like new and has been exceptionally well maintained since I purchased it on 20 December 2022. I have changed the engine oil and filters every 5,000 miles. The spark plugs, gearbox oil and filter, and differential oil were all replaced when I bought the car (invoices available as proof). Thanks to this level of maintenance, the car still drives like new. I am only selling it because I am looking to upgrade.
