American Motors introduced the automobile industry's first 12-month or bumper-to-bumper warranty, called the "Buyer Protection Plan". Its foundation was an emphasis on quality and durability, improved production by reducing the number of models and increasing the level of standard equipment. The new warranty included an innovative promise to customers that AMC would repair anything wrong with the car (except for tires). Owners were provided with a toll-free number to the company, as well as a free loaner car if a warranty repair took overnight. Numerous production and product improvements would result in fewer warranty claims, better public relations, and greater customer satisfaction and loyalty.
