Now that I look closer at the ad, I see that the "turbines" are curved, while mine are straight. The extension of the fins looks the same to me. The cap & spinner didn't come with the wheels, they were something the shop had that I purchased the wheels from... they offered a wide variety of types to choose from. The wheels are definitely not '82 Collector Edition wheels.
I wasn't looking for Motion wheels when I purchased them 7 years ago... I was looking for something that matched the real GM Mako Shark... I was just amused when I ran across this ad the other day. I'm very happy with my wheels no matter what the deal is on them
