What is it worth?

I have a 92 Jeep Cherokee Laredo. According to the Kelly Blue Book it is worth roughly $2200. Unfortunately there is a very good chance that my rod bearings need to be replaced/repaired or I suppose they may be too far gone. I was curious if anyone can suggest a fair private party asking price. At this point I do not know for sure if it is the rod bearings but my father who has an inkling about cars and the nice guy from AAA both suggesting that was it from the knocking noise. Any replies are welcome and appreciated. Thanks.
