The GMC Sprint is a coupe utility that was produced by the GMC division of General Motors for the 1971 1977 model years. The car-based pickup was renamed GMC Caballero for the 1978 model year and was produced through 1987. They were sold by GMC Truck dealers mainly in the United States and Canada. The Sprint/Caballero is GMC''s version of the Chevrolet El Camino. Only emblems, hub caps and trim designations differ from the Chevrolet. The GM A platform was downsized for 1978 but the Caballero and its El Camino twin used the Chevrolet Malibu station wagon''s longer-wheelbase chassis. In 1982, the rear-wheel-drive vehicle became known as the G platform as the A platform switched to front-wheel drive.
