In 1965, the Chevrolet Impala sold more than one million units in North America, setting a record that still stands today. Originally introduced in 1958, the Impala was the best-selling automobile in the United States during the 1960s. Early Impala models sported six taillights, a unique feature which, for a time, became the Impala trademark. The Impala was named after an African antelope.
