New Yamaha Disklavier: Good Price?

[buick8]

Hi, I have been offered at a dealer a new DC3 for about $40,400; a DC5 for $42,500. Is there any further room in these prices for negotiation? Pianos are about like cars, I have learned: prices all over the place. Different dealers are even posting different factory list prices on the wall. All have offered some sort of discount right off; they all seem really interested if I have a trade-in and want me to trade something in; what's this about? Thanks.
