Hey y'all, posted this in the general forum but figured I might get a little more help here. Looking at a 2016 Chevy 2500HD Z71 LTZ that only has 14K miles....the truck is listed as a certified used truck at my local GM dealer, but they bought it at an auto auction. The GM dealership where the truck was traded in sent the truck to auction after only having it on their lot for 3 days. The truck is leveled with wheels and tires, but other than that it looks to be bone stock. Is this something that I should be concerned with? I think that a certified used GM vehicle comes with 12-mo/12K mile warranty along with whatever transferable factory warranty is left....just kinda sitting here wondering why someone would basically trade in a brand new truck...I'm not wanting to buy a lemon or anything. This truck has American Force wheels on it as well as Dirt Logix shocks and control arm upgrades. It is an expensive truck, no doubt...but still a little less than the new ones. I had a 2015 Powerstroke, loved it, no issues. Traded in for a 2017 Silverado 5.3 with the 8-speed....hate the transmission, its a POS. Basically, I have three options....buy lightly used 2016 duramax with wheels/tires, buy new Duramax, or buy new Powerstroke. I cant decide and need some advice, thanks in advance and sorry for the length of this....
