I was set to buy a used Wing (late model/low mileage), but at those prices, I went with the Comfort Model which included the:
$1000 in free accessories.
I passed on the NAV package and will buy an aftermarket GPS/XM system. I couldn't see paying $2K for a system that I can purchase for less than $1K. I'm always renting bikes in different cities and want to be able to take my GPS/WX/XM with me.
