Pulling the Trigger SOON...some final Qs

[PeterNYC]

hello all....

First off, let me say that everybody has been very helpful on this site, so thanks a lot.

I am about ready to pull the trigger on a new '06 X3 (we are buying) but haad a few questions:

will do the following:

-Prem Package
-5 speed steptronic
-nav system (Wife insists on this)
-upraded airbags (again, the wife)
-bluetooth/assist
-xenon headlights
-seat warmers
-a few other add ons (bike rack, floor mats, etc)

Have some questions regarding the following:

-is the Premium sound worth it? Seems that, unlike the X5 and others, which offer up to 13 speakers, the x3 upgrade is better but still only 8 speakers.....Do i NEED to do the upgrade if i'm considering ICELINK?

-Servotronic: Our salesman said not to get this...first time I've ever seen a sales guy undersell an upgrade, so i guess maybe he's right? He said you won't know the difference

-is there any kind of BMW product that is a worthwhile phone cradle or is this something i should do aftermarket? Or does one even need it? W/Bluetooth obviously the phone will work anyplace in the car

-Privacy Glass: We like the very light tinting, but don't want this to look like a cheesy Limo....is there any range of tinting that the factory offers?

-has anybody used the Aux Power Adapter they offer? It's like $9 but not sure if it's usefu

-Also, there is a $40 Aux adapter for MP3s etc...this worth it if i am considering ICELINK, or just simply redundant?

Am i missing anything?

Thanks for all the help folks
