I'm about to leave for a Kawi dealer in my area who just got in a 2008 Vulcan 900 custom diablo black. 6,000 Miles, he says its really really really clean no scratches. KBB for it is like $5,500 . How low do you think I can get them? My limit was suppose to be like $5500 with interest and everything. I don't know what they are asking yet. This is my first motocycle purchase. Please if you have any advice. Thanks.
