Her back seems strange for some reason.. can't put my finger on it though. Might be that her hip is taller than her shoulders, but there's just something about it... might be the hip attachment to the body?
She looks alright.. straight legs as far as I can tell... um, deep chest..Nothing terribly wrong there..
Looks good for the price.
Chances are they're asking for a cash purchase to guarantee they'll be paid on the spot for the horse and not get hooped if someone doesn't pay up. Just like car dealerships will tend to knock off a certain price for a cash deal - they're guaranteed that money that day, not 5 years down the road.
