I considered buying the Honda Accord, Toyota Camry, and Nissan Altima; however I found all three of those to offer shortcomings. The Honda Accord's styling I found odd and ugly, the Toyota Camry's responses I found to be dull and slothful, and the Nissan Altima's ride was harsh and its styling looking too much like something a boy-racer would want. Then I saw the Fusion. It looked classy and sophisticated - a few people on the street thought it was a BMW until they saw the badge on the front. The car handles great, has great pep, and best of all the interior is genuinely useful - great car.
Powertrain, suspension, fit and finish (awesome, better than the Honda I drove), soft-touch materials, style, price.
Climate controls are a little low - but the redundant controls on the steering wheel are awesome.
