Does anyone have an idea of what a 1977 chrysler town and country station wagon with 90000 miles on it and in good condition is worth?

This is for a story I'm writing. I can't seem to find anything by googleing it, even though there are cars matching that description pictured.

Usually, You can obtain a vehicle's current value from Kelly Blue Book at kbb.com.? But the year of 1977 does not come up. You would have to find an antique dealer for value.

Thanks Marie. I posted on Facebook and got some great information from a high school friend and from someone I don't know.
