I have a 2010 Fusion Sport AWD (built from factory) with the 3.5L. Car is literally loaded with everything and has been bulletproof since purchase. Only warranty claim so far was a dead battery last November.
Though I'm currently shopping for a B8/B8.5 S4 as we speak, I am going to miss this car ALOT. It literally has been flawless and all the features still surprises people. It makes me real picky when I'm shopping now cause I ain't trying to settle. Never been a Ford guy either.
Fusion >>>>>>>>>>>>>>>>>>> Malibu.
2013 versions may be more aesthetically attractive but even the top of the line Titanium was a downgrade (feature and power wise) compared to my Sport. SA said that to me also.
