1973

The all-new GM trucks were introduced in 1972 for the 1973 model year. Exterior and interior design was revolutionary for the time, departing from the typical American pickup trucks of the era. Body styling was sleek and sculpted with rounded body lines (front fenders, cab and pickup box), resulting in the pickups and utilities becoming known as the "rounded-line" trucks.
