Look at all the Gypsy Vanners Americans import from England for ridiculous prices. Sure, we have plenty of spotted drafty horses here, but paying big bucks and importing a horse makes it seem more special, and is often an ego thing - "I imported this horse from (insert country here) for X amount of dollars". It happens with European warmbloods too.

Don't argue with an idiot; people watching may not be able to tell the difference
