The $75,760 MSRP is correct. The Z51 for $8005 includes the 3LT package and MRC. And the Processing Option for $12,960 represents the limited Premiere Edition package and of course the exclusivity/rarity. All the PE's have these two line items in their window sticker... I saw one today at a local dealer, unfortunately the stealership tacked on an ADM of 10K on top of this!
