Key strengths: Easy to drive / powerful
Areas for improvement: Electric windows / tyres
The car is very easy to drive and live with everyday. Yes it gets through fuel, and yes it is rather expensive to run, but it makes you feel rather special, and there's always plenty of grunt when required. I still get comments of how nice and impressive the car is, and if it wasn't for the tyres (mentioned below) it's pretty much perfect.
The I drive, which people tend to moan about, is actually simple and even intuitive to use after a few weeks.
The other moan people tend to make on this car is that the rear seats are only for children - that moan however, is probably fair. Adults can be squashed in the back, but realistically only for short journeys.
I only have two problems to report. The first being that the electric window sensor broke, meaning I couldn't close an open window - annoying, but quickly resolved under warranty by the main dealer.
The second and more annoying problem is due to the run flat tyres. These tyres are very very sensitive and prone to punctures. The punctures can't be repaired, and each tyre costs £270 to replace. In 15 years of motoring, I had never got a puncture; in 6 months with these tyres, I've had 3!!I would avoid run flats at all costs if you can. The running costs for Bmw 6 Series 4.4 V8 Automatic are normal
