well...brothers, before buying these i have checked them from every angle, first of all in pics they r shining becoz i sprayed Leather n tyre wax just before taking the pics....secondly chromed material always shine my previous rims were tooled once, they lost their shine coz tooling removes chrome, u can always see a lining impression on tooled rims could also be checked by rubbing ur finger or hand on them u can feel lining impression.
regarding these rims i think somebody removed them from his car very early after buying the car.
