Like Ian, I have the 'base' model, and I don't miss any of the extras. The rear-view backup camera would have been nice, but I really don't have any great difficulty seeing out the rear anyway (no worse than other cars I've owned). As for the energy flow graphics, I don't miss them - the more basic instruments are perfectly adequate (if not as snazzy). To me, the Tech package looked wildly overpriced.

If you're a heavy cell-phone user, than the Connection package (or whatever has the Bluetooth feature) may be worthwhile. For me, it wasn't.
