Is it a car, is it a truck, do we call it an SUV? Whatever the proper designation, the car-based pickup was a unique trend back in the day. The first years of the GMC Sprint were made on the same production line as the El Camino. They used GM’s A platform shared with the Chevrolet Chevelle station wagon/4-door sedan wheelbase. The workers on the line were ordered to simply trade them with the alternative grill, fender and tailgate emblems, and wheel trimmings. The rest of the vehicle was to remain identical to the proven to be popular El Camino and Chevelle.
