Five years ago when I was shopping for Catalinas in the 25-32' range I did a lot of comparisons between Soldboats.com data and NADA data. These were all boats that were 15 years old and newer. As a general rule, NADA values seemed to be about 20% low from actual selling prices shown in Soldboats.
However, as others have said, there's a huge variability in how the boats have been maintained, and that dictates a boat's value far more than any average valuation. You're much better off spending more for the best maintained boat.
