Well, I am thinking about buying a 2013 CC Silverado Z71 with the 6.2. I have the 5.3 right now and am pissed off that it is burning a quart and a half of oil every oil change and GM says it is "normal" so I want to get right of it before I have real problems. The 2013 appears to have been a demo vehicle and has 7,000 miles, but is still considered "new". I know I shouldn't pay full sticker or full rebated sticker, but what would be a fair amount to subtract from the deal for the miles. They said that the warranty will start when I take delivery so basically until 43,000 miles. What do you you all think? Also does the 6.2 have any major issues like the 5.3 does? I assume not since there is no AFM but any info is helpful! Thanks!
