NADA is still bullshit. I own a boat AND used car dealership, and realize that by no means makes me an expert... but we do more than two a year. The Black Book is what I use to check the market on cars... I only look at NADA when they need to know what the bank might loan. Depending on the market, especially now, NADA is a joke. As far as boats, as is with cars, some things I can't get within 2000 under NADA, and others depending on demand, I'll get 3 to 4K over. NADA is a guideline. It's only a rule of thumb when it comes to financing. Granted some people do think their pile of junk is worth a lot more than it really is though...
