what are you lookign for??? you can order factory stuff from mazda for other cars like the mazdaspeed emblem, protege emblem, etc....
protege5online.com has mp3 style mp5 badges.
if you want truly custom like "team nightmare" or whatever you can go a woodworking place and get it made in wood. thats good enough but if you are really nuts you can get it molded and recasted in metal/plastic. this is EXPENSIVE!!
nah, its a carbon fiber mazda emblem on a yellow background with blue LEDs to light up the "M". it's the newest cool thing to do along with the giant red "R"!!!!!
