Can you tell me what this car is worth?

I have a 1977 chevy Nova 4 door sedan, it has the straight six engine, around 68,000 miles on it. the body is mostly straight there are a few small dents, it had primer spots on it, there are some rust spots on the trunk, and on the rocker panels. the motor needs a complete tuneup, carb rebuild, new fuel pump, plugs, wires, oil change, battery, throttle cable, all the brakes, fuel lines, tank needs to be drained and cleaned. tires. and a paint job.. can anyone tell me what the car is worth AS IS.
