Touring w/Sport or Base w/Sport?

RCZ

Im buying touring AND modding. I figured the leather seats will fetch me more money to help pay for the new seats than would stock cloth seats. Moreover, if I decide I don't like leather...its easier to find someone who has cloth seats and will swap with you + $.

Im also going touring because of the bose system, I'm not audio crazy, but I do like a nice sounding system. I'm pretty sure the bose will be enough for me. The gripe that I have right now is whether I want the navi or not... I think that will come down to which graphite/touring/sports package car I find. If it has gps, great, if not then thats fine too.. Ill get something later down the road if at all.

The bluetooth does come in handy though, as does the aux jack in the center console...
