Congratulations.
I've both experienced, 3.0d and 3.0sd, If you can choose 3.0sd. It's quite perfect.
Logic 7 sound system is a must, you should prefer this. Comfort seats are the best option.
If you choose TV option in front, you will not watch tv but, you'll get DVD drive which is capable to play mp3 songs on DVD'S. It is also a good option.

Mine is: 2008 3.0sd, Sapphirre Black, Sport Pack, 214's, Black Exclusive Leather and Comfort Seats, Rear camera, TV option, Aluminum trim, Logic 7 Sound System..
