Impala. Chevy’s top-of-the-line model for 45 years. To commemorate the 45th Anniversary of this legendary automotive line, Fairfield Mint has brought together two of the all-time great Impalas. The 1958 Impala - the car that started it all. Complete with acres of gleaming chrome and authentic "sea gull" tailfins. And the unforgettable 1964 Impala. Long, low and mean – it packed a wollup with its 409 cid V-8. Pure Chevy Impala excitement. Get yours today!.
