I own a '15.
Everyone loves the look of the car. Number one compliment. Passengers like the ride (it's comfortable). As a driver I love the engine (low end torque FTW) and MFT. The weakest point of the car, by a mile, is the tranny. It has shifts slow with the paddles and gets jumpy with a quick slow and go. The other problem some people have complained about is the lack of physical buttons on the center stack. They're touch buttons which is interesting to use with gloves. They work though so, meh. Overall I love the car and would buy one again. /my2cents
But as mentioned previously test drive. I test drove 5 other brand new cars before I ordered my car. I didn't even have the Fusion on my original test drive plan (damn thing was too pretty and it caught my eye.)
