I would say it's within tolerance of the market. My son recently bought an 06 Dyna with 13,000 on the odometer from a HD Dealership, spotless, LOTS of extra chrome, and paid $7300.00 out the door including tax, here in Eastern NC.
Cape Coral Fl. Paid 7200. For a 2006 FXDI35 Anniversary with 20k. It was in ok condition, good thing for a lot of time and chrome polish. She looks great now!
