Well the price tag would be because she is not actually a warmblood, but a 1/2 Saddlebred 1/2 Percheron that is AWS registered. Considering some of the stuff AWS registers and licenses to breed it's basically a confirmation that the horse has 4 legs and 2 ears... so take the whole "warmblood" bit with a cup of salt.
Moving beyond that, she has a very low back. Notice in the confo shots, all of them have the back highlighted almost white by the light, this is to hide her bad back. It is quite visible in the undersaddle shots though. It depends a lot on the horse if this is going to be an issue or not, just for saddle fitting and weight bearing it may affect her, so ask the vet in the vet check. She is also a bit straight behind...
She looks like she would be a nice low level or pleasure prospect and looks to be obedient and evenly tempered. Depending on what kind of trails your husband wants to do and what the vet check says, I would consider her over the Friesian.
They say money doesn't buy happiness -- well happiness doesn't buy horses!
