Below the Westerner
The Westerner (500 units) in Frost White with plankwood trim side inserts and a "Pony Express" medallion. The interior featured stallion brown vinyl that simulated "richly tooled" leather on the seats and door panels in combination with white antelope grained vinyl and was available west of the Mississippi River.
Designed to spur interest in all of AMC's products and to generate increased sales for the company, the special wagons were limited for sale to geographical areas.
