2 cent chime in. I think i read it before, but here it is again. With the car becoming less avaiable, the price goes up. Really on the only big thing that seperates the early from later years is the emmisions on the car and big block options.
Now, for the guy that just simply wants one, any one will do unless he wants something exact, like in example a 71 w/440 & 4spd.
Unless a person wants a restored unit, again, anyone will do. With so few left, it's getting to the point that a '74 junk car will sell for thousands. Dispite the fact that you would have never paid $50 for it back in the day.
