Chevrolet Nova Custom
The 1973 model year introduced a hatchback bodystyle based on the 2-door coupe. The front and rear of the Nova were restyled, following a government mandate for vehicles to be fitted with front and rear bumpers capable of absorbing a low-speed impact of 5 mph (8.0 km/h). To go along with the bigger bumpers, stylists gave the Nova a new grille with a loosely patterned crosshatch insert and parking lights located inboard of the headlights.
An SS option remained available, but it was merely a $123 dress-up package that included a blackout grille and Rally wheels. It could be ordered with any of the Nova engines. 35,542 SS packages were installed, making 1973 the best-selling year for the option. A modified rear side window shape was also introduced, eliminating the vent windows on both two- and four-door models. A revised rear suspension was adapted from the second generation Camaro with multi-leaf springs replacing the mono-leaf springs used on Novas since the original 1962 model. By this time, six-cylinder and V8 engines were de rigueur for American compact cars, with the 307 cu in (5.03 L) and 350 cu in (5.7 L) V8s becoming fairly common. The 1973 Nova with a six-cylinder engine or 307 cu. in.(5.0 L) V8 were among the last Chevrolets to be offered with the two-speed Powerglide automatic transmission, which was in its final year.
A dressy Custom series joined the Nova line and a Custom hatchback listed for $2,701 with a six-cylinder engine. That was $173 more than the six-cylinder base-model two-door hatchback. Air conditioning added $381. Every 1973 Chevrolet Nova got side guard door beams and additional sound insulation, as well as flow-through ventilation systems. A sunroof could be installed, and fold-down rear seats were available.
