I absolutely love this car so far. Ford has come a long way in the last few years! It drives so nice, and is very quiet. I also love that it is unique in styling.
Definitely the Sync/Nav/Bluetooth system!
Larger fuel capacity. I have been a little disappointed with the fuel economy - have yet to see 20 MPG, even on the road. My daily round-trip commute is 50 miles, so I can't make it a week on 1 tank of gas. Only other complaint is that the driver's seat is a little uncomfortable for me.
