Option Package help!

[delirium]

I just would like to get a feel from you guys who have the following options, which ones you feel are must haves, which ones you can live without and why?

Here are my thoughts:
-Premium package: Must have because it comes w/ the panaramic sunroof, dimming mirrorrs & the luxury that a BMW should have.

-Technology package: Not a must have, as BMW Nav is not stellar, and although the backup camera & parking sensors are nice to have, they arent deal breakers... and can be ordered seprately anyway. Am i missing anything here? Does the Nav include any other cool features?

-Sports Package: Nice to have, though the anti roll feature seems pretty important, i am really on the fence with this one, help!

-Premium Sound Package: Nice to have, the base system should suffice.

-Cold Weather Package: I live in CA, so not a lot of sub zero temps here except for ski trips.

Any other packages/options worth mentioning?
