 I feel that my Mazda 3 deserves to be reviewed on the Edmunds website.  I purchased my 2007 Mazda 3 sedan at 40,000 miles..To make a long story short, i now have 155,000 miles currently and the 2.0 MZR (mazda reactive inline 4) keeps begging for more.  The automatic transmission, and sports manual shifts and performs flawlessly.. If you are in 3rd on the sports manual shifter at 60 MPH and shift into second, the Mazda 2.0 will do the factory 6500 rpm easily and shift past 2nd and 3rd at maximum factory RPM like melted butter on a New York baseball steak...  In conclusion i would recommend a magnaflow performance exhaust with an AEM cold air intake.. I promise you, whoever purchases the 2007 mazda 3 sedan or hatch, you will never be disappointed. Safe and sound! Safe and sound!
