I bought my wheels from LA Wheel and Tire.

I wanted OEM wheels but in a 19 size. As you know, some people buy an Inifniti brand new and within a few days, they trade the wheels for either another brand, a larger size, etc at wheel shops. Mine came off of a brand new Q50 with an estimated 150 miles of use. This company ensures the wheels are in pristine condition and roll properly before they accept them in trade so you won't get burned with out-of-round or refurbished wheels. You can deal direct online or at the Ebay store. There are close-up photos in my link - scroll down in the 2009 album.
