Hi, I am heavily considering buying a certified used Escalade ESV, probably a 2016 or 2017, maybe 2018 (I have seen 1 or 2 2019s but few and far in between) depending on what I find. What do you guys think about the year differences? Looking at reviews I am thinking either the 2017 or wait for more 2018's to come off lease and increase in supply. Looking mainly at 4wd, at least the luxury trim level. Any advice about what to look for would be appreciated. I plan on keeping this car for 6-7 years but having 2 years or so of full warranty really appeals to me until I cross the 100,000-mile mark.
