Looks nice and clean and like he took good care of it. And if the paperwork for the tranny is good to go, I'd today that motor would last forever.

diesels are just amazing, I just bought a new duramax with the Allison. Doesn't even feel like there is anything behind you and still gets great mpg for such a heavy vehicle.

whatever you do, stay away for the ford 6.0. Biggest pos ever made. My friend has out in over 10k into his truck in the last 2 years and it's an 03 with 160k on it.
