I was the 2008 Dallas Autoshow and saw these wheels on one of the models there, but I never seen them on another one. Does anybody have these?

 

Those are the "Night Spoke" 17 x 7 alloy wheels. They were released in 2007 and originally were only available on the "Sidewalk" edition convertible MCS . I haven't seen them in-person for a few years and don't know if they were ever offered on the non-special edition cars.
