We purchased our 2007 ABS Dark Orange (notice how it changes color depending on the light--cool ! ) Goldwing in May, 2007. The only accesories that we added to the bike at the time of purchase( already came with the comfort package: heated seats/heated handgrips ; the Navi package: GPS navigational system; ABS brakes ) were the CB and aluminum belly pan.
They say a Goldwing is nothing more than a frame to spend all your money adding accesories to. Here is a list of the accessories that we've added to our Goldwing so far ($12000 worth as of 1/2010):
