what does the 4.8 have over 3.0?

[longtran]

beside the engine size. hey guys, i'm new here to the X5world. i am considering an X5 soon and i am not sure what is worth buying. i know PersonaNonGrata from E90post.com. i have the e90 325 and e92 335. its time to get rid of the e90 325 and pick up an X5. i am stuck between the 3.0 and 4.8. i dont want to make the same mistake like i did for my e90. i know i should have bought the 330 over my 325 since the 330 base come with some stuff that in a 325 i would have to pay for. i was looking at some prices and the 3.0 with the options i want will add up to the 4.8 base model. what do you guys think about all this? any feedback will help.
