Besides ever hear of modding? Consider the base car the canvas and add your personal touches. Besides the integrated panels and trim glow. There are superior systems out there with million color & audio plug in etc.
Besides this is indeed a silly rumor because Chinese plastic panels and led's are not a problem for GM $$$ They are "plus sell" items.
Plus sell means you have the base car and you sell extras to increase the profit. Simple business way. So I would probably file this rumor under "have you seen the Christmas light LED selections at the china marts recently". As in sarcasm to all the ships of containers and 12 hour day non stop cheap labor lines that will produce your precious glow panels... trust on that.
