Honestly, No, I wouldn't. the truck has a lot of "Custom" features, but do you NEED a dump bed? do you have to have a lift kit thats colormatched to the color of the truck? If you built a truck, would you build it the same way? if it isn't exactly the way you would build it, I wouldn't buy it. I'd use the 7 grand and find another GMT400 in good shape and use the rest of the money to build it how I want it to be, not how someone else wanted it to be..
I agree with AM92, after looking past the flashy stuff, it's still a 17 year old truck, with 150,000 miles.
(For anyone that knows, yes mine was on CL for $9,000 but the ad was a joke and I and my friend who posted it, knew it'd NEVER bring 9 grand)
If you want it, get it.. I would just make sure it's what you want, and that's why you're buying it, and youre not buying it to get it off of your buddies hands....
