I am trying to PROVE the value of a 2003 Alumagator 21' tunnel (eagle 21 tunnel jet). It has an all Dart 540 and Lightning headers. I have the loan ampunt aproved but cannot find exactly the right way to prove the value to the bank. Gator boats has sent the bank an invoice of its current value but they will not except it so far. Is there another book value other than NADA. Any one hear of Otis?? Any ideas that might help me get this boat?? Thanks.
