I have a 2007 XL Denali with 217K on it. Love it. But it's a 14 year old truck, so there will be things you'll want to fix, depending on how well it's been cared for.a 2007 yukon denali with 107k and the 6.2. carfax report shows a long list of what appears to be a well maintained truck. i need some info on how reliable i could expect that truck to be as im on a short time span again hoping some peeps can drop me some info ontop of my searching.
