I would have to put in votes for Premium package, Technology package (although quite expensive), and Rear Climate Package. I am sure most people on the forum would probably throw in sport package. If your trying to limit cost, I think sport would be the first to throw out since your wife really wants the Technology package. The sport package is nice, but offers a slightly more aggressive ride since you can feel the tighter suspension.....

Just my two cents...
