Does anyone know of an online price guide for older automobiles?

I sometimes use www.kbb.com, but they only go back to 1987. I'm trying to evaluate some 70's and 80's cars but I don't know of an online resource to get acurate pricing. I know there are publications like NADA, the Old Car Price Guide and Hemmings but I'd like to find something online that I can use for free.

Anyone know of something?

 

To me there is not really a set price on these cars because it is really what someone wants to pay. But try Edmunds.com they have a page that you click prior to 1990.

 

I don't have the link, but I have seen some pricing for my 1978 300D through a NADA site online.

 

I did some research and founda NADA link on the OldCars.com site.

At least it gives a starting point for pricingfrom a recognized authority.
