Frank: I can't find the thread now, but I was not convinced that it was valid - the info came from a salesman. The post stated that the factory was shipping the Comp G package with the chrome 17" wheels and charging the buyer the $595 extra for that option.
Personally I think the whole idea is bogus. I was not charged any extra on my car for wheels, and nothing was mentioned about any change - if it ever happened. It was most likely just typical ignorant salesman's BS.....
