1977 280z going for??

[J_B]

Hi everyone....can anybody tell how much the book value for a stock 1977 280z(good shape) would be going for? I looked on at the blue book online, but it doesn't go back to that year. If anyone can help me out, it would be great. Or if anyone knows where i can look for the price online too, that would help. thanks!
