As a dealer I would ask you if you really need the nav system as it does jump a lot in price. There is no use in getting the nav if you don't use it. There are a lot of voice comands (over 650) and some really good wow features for this but the sound system is good in the non tech and I would not buy the 08 in a Tech. Your resale is not as high on the Tech either so factor this in. If it was 07 then I would have bought a Tech but since the new additions to the 08 Non Tech there really is not much different. Non Tech for me.
