Ready to buy a new 2010Z!

However...I am confused on what options I should pay for.

I want the roadster 6MT. Performance and a great sound system are important to me.

Is the touring model worth the extra $$$? What about the sport package?

I've never owned a vehicle with navigation, but am sure I would use it constantly because I am "directionally challenged". Is it worth it or should I just buy a Garmin?

I don't really care about leather seats. I've always had cloth. I live in SF and the car will be garaged at home.

I've also read about owners buying base and doing after market additions. Is this advisable?

What is the HomeLink® UniversalTransceiver?

What opinions can you share about the Bluetooth® Hands-free Phone System, 8-speaker Bose® audio system,XM® Satellite Radio system?

I guess my real question is if you are a Z owner, what features are you most happy with and what features do you wish you had purchased?

Thanks in advance.
