Id put it up for $5500 and work your way down to 5k or 4500 if you're not getting any bites. but im sure you wont have problems getting a minimum of 4500 if you CLEAN IT UP!!! take some good pictures too. make it look like you took immaculate care of it.
vacuum car wash and some tire cleaner can go a long way..
