Well those are the horses that are worth it! When we were in Germany I saw some phenomenal horses there. Had the pleasure of helping break a Hanovarian filly off import lines, she was worth some money. Performed really well and scored well.
What gets me, is the price tag on the knock offs. Good horses will sell when they are talented. They have to be built for the job they are doing, have the movement and temperament, be the total package to bring in the big money. The rest... are worth what someone is willing to pay, and if the price is high for that particular animal, it will sit in a field indefinitely. And the longer it sits, the harder it is to get a decent amount of money.
I've seen people go clear to Florida from Connecticut, Kentucky to California, Europe to the US to spend big money on a horse. But it isn't just any horse people do that for.
Also seen people do it for a "cheap" horse because of how good of a deal it was. With the filly... no one was biting and she was advertised everywhere. She's still for sale, because there is nothing behind her breeding but breed names and she doesn't know how to do anything. Lot's of time and money would have to go into her. I can't buy a horse because I like it. It needs to have something to back up that price tag.
Course there was the $45,000 Eventer that crashed and burned and was given away for free because they had "loss of use" insurance on her. Great mare, now she putzes around soy bean fields. She'll never be worth that again, but in her day.. man. Talk about a wonderful horse! They said she could never be ridden again, but she actually came around with a year off and chiropractic care. Back then I didn't have the money to take her on (boarding, vet, ect) but the guy that ended up taking her sure is lucky now. That was 8 years ago, he never did breed her but instead let his young girls use her as a schooling horse.
The one horse I kick myself over... was over in Germany. She was very well bred, scored great at her inspection, but I didn't buy her because she was in foal. She was priced at 15000 euro, bred to a Cremallo Stud (one of those color breeders that exports most everything to the US) but the stud had a lot going for him. He scored awesome at his inspection, and was doing well in Dressage. Resulting foal was a Palamino stud colt that sold to Ireland for 45000 euro at 7 months old. Dang it! That was 4 years ago and I still kick myself over it.
