Picked it up yesterday. I was about 6K upside down on an Elantra I bought in January of last year (my trade) and went out the door at right at 40K, which I figure is bad, but not nearly as bad as it could have been. I love this truck and have wanted a Sierra for some time now. I haven't given GM a chance since the 80s, and the quality is very apparent to me now. I put 150 miles on it yesterday, figured out the bluetooth (which is a lot different than the blue tooth in my Elantra. The only complaint I have is the driver's door sticks out a bit further when closed than the driver's side rear, and you can see there is a bit of a misalignment. I'll get the dealer to adjust when I take it in next week for the uncoating/paint sealer, blah blah blah. Hope the gas mileage treats me well - we'll see!
