I look for 250 Ninja's everyday (pregens). I like turning them into cafe racers. What I see all the time are bikes way over priced. They never sell. Better off buying new if you are looking for a late model bike. Me I would not consider a 300 when the 400's are available for only a few bucks more.
Local NJ dealer has 300 for $52 a month, 400 for $62 a month and 650's for $76 a month nothing down. Me I pay cash, but $62 bucks a month
