Whats a turbo caravan worth?

I think those things are just old enough to be interesting again, even stock. They aren't a barn burner the way they popped out of the factory but they were fun. I drove a non turbo 5 speed 2.2 84 Plymouth Voyager for awhile and it was a fun, useful van.
I'd say the one you are looking at is a must get for free, although I don't think it's worth more than $1500 in any condition.
