I was going through and helping my Mom clean out her garage the other day when I came across several volumes of my Fathers old Chilton paint guides. They are for GM cars and trucks dating from 1970-1985. They are complete and even have all of the actual paint chips for every color offered for each year.

Quick question, are these old guides actually worth anything anymore, or are they just a nice to look through?

Not looking to sell them...just curious.
