In 1961, Chevrolet introduced the Monza upscale trim to the four-door sedans and the club coupe body styles. With its newly introduced four-speed floor-mounted transmission, DeLuxe vinyl bucket seats, and upscale trim, the Monza Club Coupe gained in sales, as nearly 110,000 were produced along with 33,745 Monza four-door sedans. The four-speed Monza caught the attention of the younger market and was sometimes referred to as "the poor man's Porsche" in various car magazines. The Monza series contributed to about half of the Corvair sales in 1961.
