Hello Frumious Bandersnatch,

(my favorite poem of all time, btw)

Below is a website for antique car prices. Be sure to navigate the
site to understand the rating system used to determine the overall
condition of the vehicle. There is an explanation page on the site.
Since you don't say what body style it is I couldn't hazard a guess.
Convertibles and coupes are worth much more than 4 door sedans. The
more information you have (options, special features, etc) the more
accurate the estimate will be. You might also pick up a copy of the
latest Old Car Price Guide from the local bookstore.

You might also try looking in the phone book for antique car
appraisers. Hemmings Motor News is a good place to see what similar
cars are selling for. I would try to sell it locally first with an ad
in the paper or a sign in the window in front of your house. You don't
say where you live but there are enthusiasts in every corner of the
globe.No need to pay for a nationwide ad if the guy down the road
wants to buy it.

If that doesn't work, then I'd try Hemmings. They have an online
version of the magazine as well.

If you have any pictures of the car I'd be interested in seeing it.
