Nothing
I was lucky enough to get my Fusion as my first car. I almost got stuck with a 2001 Windstar Sport, but my mother traded that towards her Edge. Then I almost got a 2004 Dodge Dakota, but I was too tall for it. I also almost got a 2003 Taurus that my grandmother doesn't use, a 1998(around there) Taurus station wagon my grandfather doesn't drive. I also looked at older Fusions and the 2008-09 Taurus, and the 2008 Escape, as well as several others (Avenger, RX-8, Tiburon, Mazda 3, Mazda 6) but I ultimately picked out my Fusion, and I am so glad that I did.
