Seller is out to lunch with that price. http://www.hemmings.com/classifieds/cars-for-sale/ford/country-squire/1828367.html
I'd need more than two pics to tell whether the price is unreasonable. If it's really sharp, $15k might be a decent number.
Yes, it was optional, but I'd bet any amount this one does not have it. Does not look nearly high option enough.
What's a "Factory rebuilt" engine?? Lots of 70's cars were strangely optioned because lots of those groovy 70's people were strangely optioned.
It's now on ebay for nearly $20K. Makes sense to me. If you can't sell it at $15K, raise the price. By the way, the woodgrain is not authentic. For that money, this should be restored or pristinely preserved -- everything functioning (correctly) and everything authentic/correct.
