Even top show horses buck, moo jumps with all fours in the air like a kangeroo when she is feeling well, whats wrong with that
I think Vega is worth $5000 + if you bought her for $4500 and she has improved, she is definitely one of the nicest coloured appys I have ever seen. Its better to put them up for a slightly higher price because who ever buys them will try and get the price down a bit anyway
You could always advertise and see how much interest you get :) and if any suitable owners come along
A good horse can never be a bad colour...
