That sounds like a pretty cool set up!
A friend has a documented 1 of 1 1964 Chrysler 4 door 413 4 speed. If the wagon is rare and can be documented, then it should be worth something. Wagons seem to be kind of trendy now.
Here is my friend's car (he owns the teal '61, too).
He is not afraid to wind it up, either!
Let's see some pics of the wagon!
