That is a hard car to put a value on. To the right group of buyers it could very well do 3500 or 4000.
My gut tells me it is worth 2500 and that is to someone looking for one, but I am not in the market for a car such as this. This is a relatively popular car among rich athletes, one that they can throw another 20k into and make it awesome, so you might find someone looking specifically for a great project car. Sounds like you have one.
Your best bet is to put it on eBay and let it sit there at least a week. Don't get discouraged if the price is not moving fast, the last few hours is when most of the bidding happens. But you need it there at least a week for the exposure.
Good luck and hope you get what you want out of it. Who knows, it might go for 6 grand if you get a bidding war going.
