We are still looking for a reasonably priced 2017 LTZ or Denali that is not a rust bucket. We found one last year that looked great. Under the hood was clean. The frame however, told a totally different story. Lots of deep rust in the 50K miles so, either lots of beach time or road salt, either way, we did not even drive it. Looked at one on the web last week. Our color outside and inside. Carafax showed two owners. The first owner had it for three years and put however many miles, not that many as I recall. The second owner however, only had the vehicle for 500 miles. Maybe he defaulted on the purchase or maybe he discovered why the first owner sold it. Price was really good (low trade level, first flag).
