I was at my local BMW dealer and saw the new X6 xDrive 50i. The manager told me that they've just received 4 cars and they were all pre-sold. There was one Black X6 being prepared for delivery, and it had new 21" style 275 wheels installed. The car looked very nice and sharp on those wheels.
I couldn't take the car for a test ride because they were all sold and ready for delivery. So I got into the car just to check out the engine. When I turned the ignition on, you can hear the throaty exhaust, which is loud when you hit the gas, in a good way, and has a nicely toned roar at idle. I know the sound of M5/M6, but honestly, I think X6 sounded louder.
I took a few pics of the car...enjoy
