I test drove 6 cars before making my choice. Mazda 6, Mazda3, Honda Civic Si, Honda Accord, Fusion I4, and Fusion SE V6. The sport package added to the SE version of the V6 Fusion was absolutely smooth and responsive. Granted the Accord is a great car, but the '08 version is just to big for my taste.
The leather and cloth combination sport interior is by far my favorite aspect of this car. A huge step up from the Civic Si's similar premium cloth interior. Second favorite is the smooth V6. I find myself just cruising along at high speed not realizing that I'm speeding.
To make the v6 even better I would like to see some sort of cylinder management system to increase the fuel mileage of the v6 model.
