2008 BMW 6 Series 650i 2dr Convertible (4.8L 8cyl 6M)
Got an '08 Sapphire Black convertible with saddle leather. Awesome to drive. Extremely responsive steering and brakes. Doesn't feel like the heavy car that it is. Ample power and acceleration through all gears although could be quicker off the line. First time user of iDrive and find it to be much more intuitive then car magazine editor's complaints. Fuel economy is better then expected. Getting 26+ mpg on highways with 18 in city driving. Interior noise is also better then expected. The back panel window really cuts down on both noise and turbulence. Only complaint is that the rear speakers seem to be under amped and some navigational clumsiness between iDrive commands.
Driving this car is a blast. It is very responsive to driver commands and feels well connected to the road. Quiet interior. Not many of these models around so you get noticed.
Speaker amplification and fader balance. Easier transition between iDrive components such as moving from Entertainment to Communication screens (admit that I haven't programmed many voice commands though).
