At the end of the day, I already own an 04 4.4 with my 06 3.0 6 speed due any week now. I'll leave the slushbox to my wife. I had to fight with my dealer to get the 6 speed. Now that its upon me, I've already got my mind thinking about the possibilities. At 260lbs of torque on the S54 (which is readily available in Los Angeles) this is more than our stock 3.0's, is it not? As for supercharging...I suppose...I know this is the cheaper route. But I'm not a fan of artificial aspiration. As for getting a 3 series touring...I saw that car that Ben did. A small wagon is not my thing, but I can appreciate what went into that project. I may end up doing nothing altogether, but I'm already giving it some thought.
