02 gp gt worth trade

hey all, just curious if any one knew what i can expect for trade in value. i got a 2002 gp gt, fully loaded, leather, bose, onstar, every available option. the cars red fire metalic (maroon with gold flake) and has 40k. good tires, 2 very small light door dings on the back doors. very clean and 20%tinted windows. just wandering if any ones done any tradeing recently with all the deals going on. NADA says 11900$.
thanks
