I found my 2013 LTZ on eBay a year ago. Yes, eBay. Three years old , pristine, with 16K on the clock. It has been a gem, no issues at all. The seller even took my 2011 LT gasser with 88K miles in trade. Both were 2wd, I really don't have a need for a 4x4. Going from a gasser to a diesel was the best thing I ever did.
