At the beginning of my career I worked at a Montgomery Ward Auto Center here in Southern California. ALL of the department parts inventory was structured and controlled by the corporate bosses in the Chicago headquarters. We were forced to carry a full line of exhaust system parts, headpipes, mufflers and tail pipes. We were always in trouble, as were all of the southwestern states stores, because we never sold enough of these the meet their quota. They never seemed to be able to figure out that where it doesn't snow exhaust systems tend to last pretty much forever...
