I just bought a 2015 Sierra Denali. 5.3, Crew cab, std bed, 4WD in Onyx black. This truck is amazing. I had been going back and forth between a Silverado LTZ and this, but this just spoke to me, so I pulled the trigger tonight. I'm coming from a small Bmw sedan, so driving this beast will take some getting used to. I bought a very lightly optioned model as I felt that would be the best way to make it my own. I look forward to hearing and reading about all your experiences with this fine truck. Here is a couple shot of her in the dealership tonight.
