1920-1970

This category generally includes all eras of collector cars. Special Interest autos are identified as automobiles which have appeal for various reasons of engineering and/or style. Many automobile factory show cars and celebrity cars of all eras fit in this category. No typical styling features can be assigned to this group, but all unique and unusual autos can generally be categorized as "Special Interest."

This category encompasses the historically significant unique automobiles that don't fit easily into other categories. Often it is only in the eyes of the beholder that a car qualifies as "Special Interest." Both styling and engineering factors can be reasons for inclusion in this category. Innovative autos such as the Chrysler and DeSoto Airflows, the revolutionary Tucker, and first-year engineering efforts such as the 1949 Cadillac (the first year of the new overhead valve V-8), and the 1955 Chevrolet V-8 Nomad station wagon, qualify.
