I am sure a lot of Civic driver here had experienced driving a Mazda3.
I am wondering why you chose the Civic instead of Mazda3? Do you feel Civic is "quieter" than Mazda3?
I am deciding between these two models, actually I am more biased to Civic EX but the wife likes MAzda3's zoom and leather/heated seats. But she also noted that Mazda3 seems noisier driving on highway than Civic EX...
Hope you can share experiences especially from those people who owns both!
