I got the base model X with A/C and that was enough for me. Radio is decent enough, not like you will be able to hear it much at highway speeds without blaring it.
As far as power group and everything, I did without.. I'm not a fan of electronic seats and windows.. And the aluminum wheels are nice, but I was planning on swapping them out for some aftermarket anyways, so i didn't pay any more for the upgraded stock ones.
