Book value Is about $4200, but with the low miles and that color combo I would say trckdrvr's estimate of 6k should be about right. With only 230 miles that could make a difference, you might take it by an HD dealer and ask them.
6-8K if you don't mind waiting and filtering the low balling idiots.. CL is the best way but be warned of scammers. The only way to list and sell it there is to make sure and only respond to people who email a name and number, if they don't include it don't respond, under no circumstances!
