And I...
have three (amount of rims I have) rims for an 04 Mazda 3. I'm pretty sure I can't really beat the offer of the post above me but since theres only three I'd be willing to make a good deal so it's worth a shot :)
haha
Have some
I have an old set of three rims (ones busted) for my 2004 3. I'm not SURE that they're 16 but if you post back I'd be happy to check. Also I realize that you'll need 4 rims instead of 3 but I'd be willing to make a low-price deal so that you'd be 3/4 of the way there :)
