I found a 72 Polara. Price?

I have been looking for another 72 Polara ever since I sold mine last year. I found one and it looks to be in fairly nice shape. It is loaded. Power everything. Bucket seats. Fresh paint. They stripped it to bare metal and repaired some rust spots. The car looks great. It is a 2-door and it has a 440. It seems like everything I want. It is even the right color. Black. No vinyl top either. Everything works.

Here's my question. What is a fair price for a car like this? I'm not going to tell you what they guy is asking for it. I just want to make sure that I'm not overpaying. Thanks!
