A 1950 Ford Custom Deluxe Convertible with black exterior and red interior is a classic "shoebox" Ford featuring a 239 CID Flathead V8, 3-speed manual transmission, and power black canvas top. The iconic black exterior is accented by chrome trim and whitewall tires. The restored, high-contrast interior typically features red leather or vinyl bench seats, a painted dashboard, and a large, original-style steering wheel.
All the goodies; V-8 Flat-head engine, three speed on the column, dual spotlights, mirrors, dual-exhaust, front and rear bumper guards, even fender skirts, steering knob with pinup girl (also called suicide-knob or necker-knob). Even a clock and radio... woweee! And who wouldn't want a "coon tail" flying from the antenna? White-wall tires.....man oh man... how cool is this?
Two twin brothers at my high school in Oklahoma City drove these '50 model Fords, although theirs were hardtops, they were so cool and everybody drooled when they drove by.
This body style was nicknamed "the shoe-box" because of its lines and that name has stuck 'til today... You mention a shoe-box and car folks know what you're talking about.
