In 2010, when my wife and I were having our anniversary dinner, a group of cross-dressing men came into the restaurant. These weren't men pretending to be women, they were simply some dudes who liked wearing women's clothing on occasion.

That's how I view the full size, luxury SUVs based on corporate siblings. The Escalade is simply a Tahoe with pearl earrings and a feather boa; the Navigator is an Expedition in platforms and fishnet stockings; the Infiniti QX80 is an Armada with too much blush and eyeliner, etc.
