We are in the market for an Yukon XL Denali I’ve looked at a few low mile 17s that are nearly perfect but for about 7-8k more it looks like we could go new. I realize the warranty differences/advantages but I really can’t quantify the 10 speed and new grill/active shutter differences. Is it worth the premium in the long run. We could also wait a bit, as we don’t have to have it this month and see if 2018 prices fall a bit more?
