The 1957 Chevrolet sedan delivery is a rare find. Though many were produced in the late 50's, because they were used as work vehicles, few are left and even fewer are in good shape. They were built to use as milk trucks, delivering groceries, stuff like that, and they used them up and then they were gone. Many just rotted out. The 1957 Chevy delivery is a sought-after collectible among car enthusiasts. Chevy only produced the delivery sedan for four years before it was phased out in 1960.
