By '63, the Impala was offered in six models, including six- and nine-passenger wagons. Even in the regular sedans, Chevy prided itself on how much space the consumer had, both in the cabin and in the trunk, seen in the low, long exterior. Luxury and comfort were just as important as sport and style at this point. Don't think they sacrificed style, though. This is one of the most sought-after models of the Impala, with its pointed front and rear edges, aluminum striped rear, and a sunken instrument panel. The company added "hot or cold" engine lights in the dash,"air-washed" rocker panels, stainless steal mufflers, and "self-adjusting safety-master" brakes to help reduce wear, and introduced all-season air conditioning and Delcotron generators in the Impalas.
