Since Grand Am was an "in-between", its sales declined and the model was discontinued in 1975. 1973 The Grand Am, coined by Pontiac with a name derived from two other cars in its lineup ("Grand" signifying "Grand Prix luxury" and "Am" for "Trans Am performance") was designed as America's answer to European luxury/sport sedans and available as a four-door Colonnade sedan or a two-door Colonnade coupe.
