As a family we needed a third vehicle to cover our increasing transportation needs. We own a van and an SUV and thought a sedan would balance out the family vehicle situation. We bought this car after realizing that though many Civics and Camrys out there would certainly do, many were abused by their previous owners and made for a pretty shabby used car. The local Mazda dealer explained how Mazda owners tend to have a special bond with their car and treat it nicer, and after about a week with the Mazda6 I could completely understand why. I'll never buy from another car manufacturer again. Even though its a rock bottom base model, it still evokes some jealousy in my friends. They can't tell.
Such a smooth ride, love the shiftable automatic transmission. Interior feels more like a sports car than a family sedan. Having a hatch but with sedan styling is perfect. Wish all cars were like that. Even though its 6 years old, it still gets about 27 mpg, much better than you'd expect really.
Very few. My only complaint has been that the side front grill pieces have a tendency to pop backward out of their holes (when i go through the car wash and such). They stay in a small pocket behind the hole, and can be easily retrieved. You may have some trouble snapping it back in though.
