 I have had my 6 for 9 months (~9000 miles). Love the exterior and the performance.  I am a little disappointed in the fuel economy.  I guess I miss my turbo Saab mileage.  I have to have the brake rotors replaced as they are already warped even though I am VERY easy on my brakes.  The car also seems to have a "niggly" vibration as the engine revs pass through 2500 RPM.  Overall the car is a great value, handles well, loads of power, love the engine growl. My original choice was going to be either a BMW 3 series or an Infinity G35 sedan. The Mazda 6 convinced me I didn't need to spend the extra cash to get what I wanted.  Great job Mazda.
