Much more info is needed to give a realistic appraisal of "fair" market value. The more pics, and the better the quality of the pics, the better the appraisal. What is the nature of it's "non-running" status. How long has it been sitting? Inside or outside? How are the tires? Will it crank? How many miles on the clock? How is the paint?

Many, many pics are probably the best tool you can use to get a decent estimate of what it might sell for. As a non-runner, it could be anywhere from scrap value up to who knows what.
