I just thought it was interesting that an aftermarket company decided to take the gamble and bring back such an archaic, and antiquated, mod.lol
The new Camaro is supposed to be a "Retro" design, but I really don't remember seeing any 60's Camaros with rear window louvers.
I'd still like to see a Crossfire with a well done rear window louver on the hatch, just something a little different. I think it's a "look" the XF could pull off.
