Sure the book price is getting lower and lower, but hey, if i put thousands into my gtp, and it got wrote off, i'd be finding out how to get most if not all my mods out and off of it, to eithor put on another gp, or to sell. Like if the op got $3500 for it, and is able to get most of his parts he wants off, i wouldn't be complaning. $3500 is more then what 95% of 97-03s sell for, even if he just sells the parts and moves on to a different platform.
Sucks that that type of **** happened to ya man, but what can you do. If you've got the check from the insurance company, i'd leave it at that
