[Duke I]

From a performance standpoint, the M40i has definite and clear advantages, but these may not be important enough to or better enough for you for the extra $. In my case, I keep my cars for a long time so because this car is my DD, I was attracted by the hardened chassis and upgraded brakes, engine and drivetrain mechanics -- I'm expecting this will mean many years of enjoyable and carefree driving.

As an aside, the car is great in the winter snow. My ski area has gotten more than 300" (I've also had to plow my driveway 18 times this winter) and the X4 gets me up the mountain reliably, regardless of the conditions -- the Hakkas help out too!
