i own a 2002 Denali AWD I bought new right after 9/11. At 135,000 miles I have done recommended maintenance, synthetic oil all the way. Never uses a drop. Issues: replaced electric fan, a/c compressor, autoride shocks, which was not cheap -- but the truck drove like new after. On the third set of tires and did not do brakes until 110,000 miles. I just bought a 2013 Escalade with 36,000 miles, but at $5000 best (dealer offered $4k for trade which I rejected), I still own the Yukon. So it's the truck that will not die. I really like the Escalade, but while the Escalade doesn't know it's a truck, the Yukon surely does.
