Bad news if you were hoping to get your mitts on the ZR1 rolling chassis GM put up for auction a while back. Looks like the company has yanked the nekked chassis from the upcoming Barrett-Jackson auction. The company hasn’t released any details as to why the rolling framework, complete with its supercharged LS9, got yanked. Maybe someone at GM just couldn’t part with the ride. Or maybe they’ve already sold it. If you see Jay Leno cruising around in a body-less ZR1, you’ll know what happened. [Source: Barret-Jackson]
