Bought this car for my wife who was reluctant to own since she doesn't like the tight, sports car like ride. She prefers the soft, floating on air feel. Well, it's mine now. The X3 has a lot of get up and go, and you just have to breathe on the brakes to stop the vehicle. On the highway, you need self-control to keep it under 100 mph. It's like riding on a rail. However, around town in stop and go traffic, it is not smooth acceleration and shifting. It lurches off the line and then quickly starts upshifting. It's what my wife did not like about it, and I have to agree. All things considered, it is an awesome vehicle and has a real class aura about it. I highly recommend it.
The looks, the highway ride, the engineering, the attention to quality, the vista moonroof, the heated steering wheel, the monaco blue color.
Gas mileage is ok, not great. The "unsmooth" acceleration really is disturbing. I brought it back to BMW where they re-programmed the transmission, it didn't help.
