i believe the vette and the h4..the rest i must question but then again...the ss is suppose to go against the gt500 cobra if it does and gm h olds true to the past...all the camaros had more horses than the must counterparts always so 30 more horses than the gt500 sounds about right. the hardest one to believe are the caddy ones. we haven't even heard rumours about the cien but we know the sixteen is coming we saw the clay models for it...i heard they weren't going ot do a v16 though and just do a v12 for it. but I'm sure NAIS will be an awesome show.
