Kelley Blue Book only offers used car valuations for vehicles produced since 1992. Two other trusted sites that offer valuation estimates for antique and classic cars are NADA Guides and Hemmings, found at NADAGuides.com and Hemmings.com, respectively.
NADA Guides provides Original MSRP, as well as low, average and high retail prices for a particular vehicle. A search can be initiated by clicking the Classic Cars button at the top of the Home Page, and then clicking the yellow Start Here button. The rest of the process includes selecting a make, model, year and optional features to yield the pricing information for a specific vehicle. The search option for optional features can be left open to produce values for a particular model in general.
The search feature on Hemmings is similar. Click on the Price Guides link found under the Classifieds tab at the top of the web site. Next, enter a year, select a make and model, and then click the green Check Pricing Data button. The results page yields Original MSRP, low, average and high prices for used marketplace listings around the Internet.
It is important to note the valuation information provided by any source are guidelines, and many factors can go into consideration when determining the value of an antique vehicle.
