Also, I think the days of really cheap bikes on CL are gone. There is no means of searching what bikes are selling for in CL only listed. In the end its only worth what someone will pay. The issues is the raising cost of new bikes. It tends to make the used ones worth more. KBB and NADA don't reflect that much.
Currently cleaning up a couple of used dirt bikes to sell for a new purchase. Hard to price what they are worth, but if what folks are asking on CL is any indication with a bit of polish, a few bucks in inexpensive cosmetic parts, and removal of aftermarket parts for separate sale I maybe able to come out nicely with the new purchase.
Buy high, sell low. That's my philosophy. Well, not my philosophy, it's my reality.
