i think one of the models of huyudai excells have 4 x 114.3 13 inch rims. other wise elantras have 14 inch and the just replaced lancers have a 4 x 114.3 15 inch steely. all the offsets are wrong though, except if you want spacers.

as for 13's, old corollas had decent offsets for them and were 114.3. should be plentiful too.
ke's and stuff at the wreckers.
