what so you think it is worth

Well, with those pics, it's impossible to tell condition. I think your price range is between $1000 and $3000 depending on condition. Unless it's rusted out badly underneath to the point where it's a parts car, but even then I'd say $600 because there's probably more than that in parts on it.

I'd check it out REAL good because that might not be original paint and could be hiding bondo or rust. In the pics, unless it's just bad color, I don't think that even looks like a factory color. Check the jams and under the hood, trunk for original color, and check o/a for signs of repaint unless it's obvious.
