The 1963 Chevy II remained a unibody design with a 110-inch wheelbase, sold in 100 and 300 trim levels. A new grille had thicker horizontal bars, and Chevrolet lettering on the hood replaced a badge. The 100 series lacked side trim, while the 300 had body side moldings, and bright window reveals. The top-level 1963 Chevy II Nova also had rocker moldings and its name on the rear fenders.

The 100 and 300 lines offered two- and four-door Sedans and a six-passenger Station Wagon, while the luxury Nova added a Sport Coupe and Convertible. Prices ranged from $2,003 for the basic 100 Sedan to $2,472 for the Nova Convertible. Base engines remained the 90 bhp, 153 cid four and the 120 bhp, 194 cid six. Chevy II sales climbed by 50,000 cars to 375,600 units for 1963.

While sales of the four-cylinder languished, the sporting side of the Nova was coming on fast. New for 1963 was the Nova Super Sport option, a $161.40 SS package that included a special gauge cluster, all vinyl interior with front bucket seats, extra chrome trim and a console. A total of 42,232 buyers upgraded the 1963 Nova Sport Coupe and Convertible to SS status.

Chevy still didn’t offer a V-8 in the SS package but buyers could have dealers install 283 cid or 327 cid V-8s at great cost. Motor Trend’s Bob McVay took his Nova SS test car to a Los Angeles dealer and was quoted $1,555 for a 327 V-8 conversion, including a 4-speed gearbox and Positraction rear axle.

Other options included air-conditioning, Powerglide transmission, power brakes, power steering, Nova front bucket seats, power convertible top, wire wheel covers, Positraction axle, front seat belts, pushbutton radio, tinted glass, two-tone paint, heavy duty clutch, heavy duty rear shocks, heavy duty springs, and heavy duty radiator.

Chevrolet offered 15 exterior colors for 1963 and 11 two-tones, including Tuxedo Black, Laurel Green, Ivy Green, Silver Blue, Monaco Blue, Azure Aqua, Marine Aqua, Autumn Gold, Ember Red, Saddle Tan, Cordovan Brown, Ermine White, Adobe Beige, Satin Silver, and Palomar Red.

In 1963 Chevrolet offered the widest range of cars it had ever built, and three of every 10 cars sold in the U.S. were Chevrolets. Model year sales of Chevrolets and Chevy IIs reached 1,947,300 units.
