The fourth-generation El Camino (1973-1977) was the largest yet, boasting a two-door Chevelle wagon platform with bumpers that could absorb a small asteroid. Think Malibu interior with a twist, and you’ve got the Classic model. Handling was as smooth as a jazz sax thanks to a wider wheel track and computer-designed coil springs. Engine options ranged from “get me there” to “hold my coffee,” peaking with a 454-cubic-inch beast. New features included swivel seats, turbine wheels, and a gas tank that could outlast your bladder.
