If it is in fact a real-deal Z-16, then wouldn't the seller want to maximize his sales effort, and at least take some decent pictures? There is alot of missing info, like is the original rearend there, if so it should have the extra bracing, cowl tag info, remote mirror, dash top clock, original emblems (are the holes there? cant see enough in the pics). Seems like it might be real, but why leave so much doubt about it. If this is a classic car resto shop, you think they would know to advertise better.
