C2 Corvettes VALUE??

I have been following C2 prices recently and I see lots for sale but not sure what they are actually trading hands for, I am curious what informed people think about these prices and are they likely to hold their value. The only info I have been getting is from sellers that hope to get the most they can, don't blame them just would like to hear from experienced folks. I like the looks but not sure I understand the value. Thanks
