Dealers will want to really low ball you so I'd try and advertise and sell it yourself. I bought a new X series a couple months back and the dealer offered me $2500.00 for my old Lazer Z. Almost killed the deal, told him I'd just keep it for that. It's worth whatever you feel it is and what the market will bear. Check places like Craigslist for similar models and see what's currently out there. Just throwing a number out there without seeing it I'd say a good starting price for negotiation would be somewhere around $5200.
