Hello, I am currently in the market for a Denali XL or Suburban. I’m looking for one that is fully loaded. My wife is set on second row bench as opposed to buckets which are hard to come by. I found a 2 owner pearl white 2011 with 135,000 that appears to be nice from the pictures I saw. It is listed at $16,400. I also found a single owner 2013 black one with 180,000 miles listed at $15,500. Anybody have any input? Also, what should I look for when looking at these as I have never bought GMC.
