I was interested in purchasing a used 3560 either 2005 or 2006. The performance numbers seem hard to match along with great fuel economy in a boat that large. My question is what did these boats retail for back in 2005/2006? I thought this boat cost about the same as a sea ray 340 dancer but the used values i see on boattrader and yachtworld are much higher then the 340. Can anyone help me out? I want to make a fair offer.
