High Quality Content by WIKIPEDIA articles! The GMC Sprint is a coupe utility that was produced by the GMC division of General Motors for the 1971–1977 model years. The Sprint was renamed Caballero for the 1978 model year and was produced through 1987. The rear-wheel-drive car based pick-ups 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. Trim designations, emblems, and wheel trim differentiate the GMC from the Chevrolet. The GM A platform was downsized for 1978, but the Caballero used the Chevrolet Malibu station wagon`s longer-wheelbase chassis. In 1982, the vehicle became the G platform as the A platform switched to front-wheel drive.
