[4] While in production, the Series S-10, which was sold with the trim package DeLuxe, was DeSoto's entry-level car, and was offered primarily as two-door and four-door sedans while the Custom offered upscale interiors and appearance including a 7-passenger sedan[2] and the extended-wheelbase Suburban sedans.

[7] Deluxes produced during the 1946, 1947, 1948 and first half of the 1949 model years used DeSoto's prewar bodies, slightly updated following the end of World War II.

In 1950, the Custom gained DeSoto's first station wagon body style, which was not offered as a Deluxe and gave the choice of optional wooden panels bonded to the exterior steel body.

[2] The Custom also received DeSoto's first hardtop coupe, which featured pillarless door design and offered interior equipment and refinement from the convertible, and again, the Deluxe was excluded from the premium body style.

[2] Standard equipment included two-speed electric windshield wipers, a trunk light and full carpeting.
