I come from a Honda family. We own a 95 Civic, 04 & 08 Accords. My mother has owned three Camrys, including an 09. I regularly drive the Camry. The Fusion is right up there with the Hondas and the Camry. In fact, it's quieter than the Hondas and the Camry. Totally trouble free with over 20k miles in the year+ I've owned it. You would make a mistake buying a midsize care without checking out the Fusion.
Speed control can be set/increased/decreased incrementally. Very quiet and controlled under all driving conditions.
V6 engine could be more refined, like the Accord. Mileage is not bad(26-27 mpg) but could be better.
