How do I find the value on a car that is over 20 years old?

The Kelley Blue Book offers an "Early Model Guide, Collectors Edition" that gives the value of cars from 21 years old up until models made in 1946. It's possible to order this book or get a subscription by contacting Kelly Blue Book through its website or telephone number.

To avoid buying the book, consumers have the option of finding older copies of it at libraries, credit unions, and other places of business. Both the book and the website contain the values of most car models. It also includes listings for powersport vehicles, including ratings for snowmobiles, ATVs, motorcycles and personal watercraft.
