Over the interwebs it's impossible to give an accurate estimate on a vehicles value completely sight unseen. Run it through NADA or KBB and see what you come up with. In purchasing any used vehicle, price should be the very last part of the negotiation. If you don't know how to completely inspect a vehicle take it to someone who does.
For reference:
Scrap value is ~ $230 usd.
Trade in from KBB is $1253
Private party from KBB is $2223
