Initial impressions: The car drives very nice. The steering is a lot less stiff compared to the 335is and it's a bit nice for a car this size. It drives very well and it's very much like a car but rides higher.
The power is there and there's still a nice exhaust sound but not nearly as loud as the 335is. Obviously driving a SUV means slowing down more at a turn which is not a big deal. I feel the urge to drive fast is not as tempting as it always was in the sports car but that's not a bad thing. It makes for a more relaxing ride for the passengers and better on the fuel economy
The one thing I still have to get used to is the braking. The brakes on the 335is were so awesome and I could stop at any point without much effort. Part of it is the extra weight on the X3 also. I definitely need to stop sooner or apply more pressure on the brake pedal in the X3 to stop in the same amount of time and distance.
