My story is a little different. I don't actually even have the Fusion with me right now. I was around when it was bought though. My fiancee (wife now) bought her grey 2010 Ford Fusion SE brand new in the summer of 2010. We were married and then moved to Okinawa, Japan in the summer of 2012. We gave the car to her parents who continued to make payments on it.
Fast forward to about a month ago. My time is coming up here in Japan and I'm more than likely moving back stateside. I worked out a deal to get the car back. It has 60K miles on it and has been taken care of so I definitely can't complain. I've had Fords for most of my life (1998 Escort ZX2, 2003 Focus ZX3, and a 2009 Focus SE).
I'm a big fan of the car and got on this site to look at possible upgrades. Nothing super crazy since I'm older and have a family now. I want to improve the already great gas mileage and possibly add new wheels and tires and performance struts and springs. I've read some good information already. I look forward to talking with each of you more.
