Only improvement I can see is LED flashers in the side mirror covers, other than that I still think I am looking good with the '17 Premium AWD.
I noticed the turn signal indicators also.
I wonder though, if the pics we're seeing are for the Asian/European markets, where the turn signal indicators on the mirrors are standard. Someone correct me if I'm wrong, but I thought I read where that feature is required by law on new vehicles in every other market except the U.S. (This may or may not be correct...) but I'm pretty sure all the European XT5's have them as standard equipment.
If Cadillac doesn't put the turn signal indicators on the mirrors on all of the 2020 XT5's, they should be ashamed of themselves.
