I am looking for used 17" black wheels for my mini cooper(dont really care what style (too much)). Please respond if you have any or know anyone who is looking to sell some. Thank you!

 

If you still want them, then instead of getting it from any individual, It is lot better to get it from some reliable online auto parts stores. They have wide variety of these stuffs, so you have more options to choose from that best suits you. One such place where you can look for your required stuff is http://www.autopartsfair.com/wheels_rims/
Give them a try.
