My wife and I are exploring the idea of purchasing a late 80's, early 90's sportfish yacht in the 40-50' range. I've been searching Yachtworld, and find there's really no rhyme or reason to the asking prices for these boats. Newer/larger boats listed for less than older/smaller ones, same make/model/year boats in similar conditional and with similar equipment listed for drastically different prices, and re-powered boats asking less than MOH/original power boats, for example. To add to the confusion, there are few resources,available to the public, to determine a fair value for this class of boat. There's NADA, but their prices are consistently $40k below most asking prices. I can't imagine too many sellers entertaining an offer that much below their asking price. Is there anyway to determine a fair offer price, w/o consulting our own broker? Any insight would be greatly appreciated.
