Hi everyone, i recently just got a standard 2006 Mazda 3 GT. So far ive only installed a sound system and tinted it but i want to go all out with it because i love mazda's (previously owned a 97 protege) and i hope you guys could give me a good guide line of where i should start off and the first little things i should be doing to improve my mazda. Other than what ive mentioned before it is completely stock. Hope to hear you guys advice and ideas. Thanks in advance.
