Is my 78 280Z worth anything?

I bought a 78 280Z many years ago with high hopes of getting it running. I have done very little other than remove the carpet because it was smelly. It came with an extra transmission. One is a 4 speed and the other is a 5 speed. I was told both were rebuilt. The car is rusty but the glass is intact. It has been in my garage for the last 12 years. Would the car or parts from the car be worth anything to anyone or should I just junk this car?
