'See the USA in Your Chevrolet' was the theme song for Dinah Shore's popular television variety show, which debuted on NBC in 1956. Ms. Shore remained a spokesperson for Chevy throughout the 1950s and early 1960s, during which time GM regularly gave her new cars for her personal use. This 1957 Bel Air convertible is one of those cars. It still wears its original one-off color and is a true survivor with only a little over 6,500 miles on it.
