I love my Mazda. It works well and I've never really had a problem with it even after someone hit me going 40 when I was at a complete stop. Not that much damage done to it when it was hit, but it did cost a few thousand dollars to get it fixed. Very fun to drive. Pretty fast (obviously not a Corvette or BMW, but still fast enough to make you happy). Very good handling and easy layout of controls (minus the power windows switch for driver. I always press the back ones on accident). Other then that I'm glad I have it. Gas could be better especially with the prices the way they are now.
The steering wheel. The sound of the engine. The speed it can handle. The handling itself. And the stereo (though I don't like that the buttons get really hot after playing a cd for a while).
Move the power window switch for the driver down more. Offer power seats, and a stiffer back seat. The back seat it way too soft.
