OK, here's the deal. I know you don't want to hear this, but I have to say it, then I'll let it go.Front and rear end body damage. It looks like the drive train is okay. The air bag did deploy but I can get one off of ebay. I read that if the repair bill is more than 30% of the car's blue book value then it's considered totaled and the insurance company won't pay to fix it.
My Mom was an insurance adjuster, so she is pretty familiar with what it takes to total a car. the number is far higher than 30%, but that number does change with the age of the car as its value decreases. The value of the car goes down, repair cost never does.
But, she was adamant to never, never, ever by a totaled car, partly because our first car was a total. It was a simple repair, but we were still finding glass in it six years down the road. But that was in 1965. Stuff is a lot more complicated now, and it is easy to have unseem damage that causes big problems down the road.
I would bet there is some frame damage on that truck.
Anyway...just had to say it, so I wouldn't feel bad if something happened.
The 2007 was the first year of the new body style and its intro was fast tracked by six months. despite this, the trucks didn't have any major problems. You might want to check some GMT900 websites. gminsidenews might be a help, too. there are a lot of techs on that site.
Good luck. Those really are nice trucks.
