I've owned the new 4.8 V-8 x5 since February. It has a great ride & with the "Sport" option it really gets up and goes. It is very fast for the size of the vehicle. It handles really well & corners without any over steer. Great ride & the engine is silky smooth. I put on most of the options & can't figure out why so many people complain about the iDrive. If you use a computer you can use the iDrive. I don't have to look & it is easy to navigate. There are a lot of options to set to your liking with the iDrive & I think that may be why people complain. Great vehicle. I'll buy a new one every 4 years or so. One last note that there isn't any maintenance dollars out of my pocket.
Sport button for handling & acceleration. The panorama sun roof.
My only slight complaint is the gas mileage. I get 20 on the hwy (keeping it under 70 mph & 15 in the city. Not too bad but I thought it would do better with a 6 speed tranny. But weighing 5000 lbs & 350 hp I guess I shouldn't complain.
