Both model years epitomize the 1950s American luxury convertible ethos—large, wide, and low with an emphasis on style and presence. Performance improvements were more engineering-focused than dimensional.

When compared to contemporaries like the 1958 Cadillac Eldorado Convertible or the Chrysler 300D Convertible, the DeSoto Adventurer I Convertible’s length of 5552 mm and width of 1989 mm positioned it firmly within the full-size luxury convertible segment.
