Sync is great for allowing you to connect your ipod/zune/thumb drive and play your music or audiobooks with hands free controls. Sirius is nice for commercial free tunes. Applink (coming soon) will allow Pandora from your smartphone.
35MPG without even trying. On long trips, I got 44MPG and the 6 speed auto gets better milage than the manual.
This is the best handling car I have EVER owned. It loves to corner and when paired with GOOD tires, it is absolutely phenomenal!
I really expected a little rattle box and was pleasantly surprised at how solid the car feels. No annoying rattles or vibrations and much quieter than my previous Ford Escape.
