シボレー・コルヴェア
For the 1960 model year, the Rambler American line added a four-door sedan body style and a third trim level, a top-of-the-line Custom. The new four-door rode on the same wheelbase as the other models and was meant to battle the newly introduced compacts from the Big Three, the Ford Falcon, Chevrolet Corvair, and Plymouth Valiant.
